With the strong focus on QT applications that everybody in this industry is experiencing, blue, violet and green wavelengths become more relevant than ever. For quantum computing wavelength of 369 nm and 399 nm (Yb+), 422 nm (Ca+) and 461 nm (Sr, Sr+) are especially important. In addition, Sr is a very prominent atom for the analysis of quantum gases thus relevant for fundamental physical research.
EAGLEYARD, who has yet primarily focused on red/infrared wavelengths is now involved in R&D activities for blue and green laser diodes with dedicated lead customers. The results are expected to yield in prototypes for the broader market during 2025/2026.
Yes, our butterfly packages are hermetically sealed.
We specialise in the development and manufacturing of semiconductor laser components and do not offer drivers or temperature controllers. However, a small selection of mounts and boards for evaluating the lasers is available. In addition, a wide range of equipment for our laser components is available on the market.
We do not offer PIC-based products as commercially-off-the-shelf products. For our core wavelength range (red to IR) the technology is not sufficiently mature nor cost efficient to integrate it into our standard offering. However, EAGLEYARD is involved in relevant research programmes to evaluate and advance PIC technology for its suitability in combination with our laser diodes. Our commercially available gain chip products are widely used as suitable gain media in combination with novel PIC structures.
Single mode lasers or RWL (ridge waveguide lasers) are laser diodes with straight waveguides. Single-mode laser diodes are a type of semiconductor laser designed to emit light in a single transverse mode, meaning the laser operates with a single spatial and longitudinal mode of light. This results in a small spectral widht (few nanometers or less) and stable beam with excellent beam quality. Single frequency lasers have similar properties, but these typ of lasers have an additional grating integarted resulting in a narrow spectral linewidth in the range of MHz or even less.
Gain chips are semiconductor device that provides optical amplification, but it is not a complete laser by itself. Often, gain chips are used in systems where an external cavity provides feedback for laser oscillation. This enables precise wavelength tuning and control.
Unfortunately we are not able to lend our customers a laser for testing purposes. Other than lasers in desktop devices our laser components are not protected against unwanted overvoltage, overheating, ESD or other impacts from outside. These impacts can lead to damages or pre-damages of the laser diode that are difficult to detect. Therefore we do not reuse lasers that have been used before, Our strict quality policy only allows the delivery of unused lasers.
USAGE
A tapered amplifier can be used to increase the output power for example of DFB lasers or other single frequency lasers such as miniECLs or macroscopic ECDLs. The advantage of the tapered amplfier is that only the power is amplified and the pure spectral properties of the seed source remains.
RWS is a word creation by TOPTICA EAGLEYARD – it stands for “Rich Waveguide Stabilized” and uses the same chip material, design and technology as classical DFB lasers – but at half the price. RWS lasers are specifically developed for industrial usage, mainly for interferometry and users that are very price sensitive. RWS lasers can make your project become reality when you need a small linewidth but are +/- 3 nm flexible with regards to the center wavelength tolerance as the RWS has a broader specification range than a DFB laser diode. We guarantee a mode-hop free range when operating conditions are set ideally. Our RWS laser is available at 780 nm – a sweet spot for great performance of the laser and sensitivity for Si detectors that are available at very low costs compared to other wavelengths making our RWS laser a real ‘cost-saver’ in purchase and (!) usage.When working with blood flow measurement in life science or industrial measurement technology like speed and distance measurement, vibration or thickness measurement make sure to check out our RWS lasers!
Our multimode laser diodes operate with both spatial and longitudinal modes, delivering flexibility across multiple applications. Constructed on GaAs wafer substrates, these laser diodes cover a wavelength range from 653 nm to 1064 nm. To fine-tune the beam shape and output power to specific needs, we provide stripe widths from 60 µm to 400 µm. Depending on the wavelength and chip design, our multimode laser diodes can achieve output powers ranging from 1 W to 18 W in continuous wave operation or up to 100W in pulse mode operation. Typ. pulse widths range from ns to µs with duty cycles up to 50%, but also QCW mode operation with ms pulses are feasible.
An RWE laser diode is a gain chip that can be used in an external cavity diode laser (ECDL).
The first version -9001 is fully compatible with laser and TEC drivers from Arroyo, ILX or controllers with similar pin confirguration. The -9002 version is compatible to controlles from Thorlabs or controllers with that pin configuration. For self build or independet controllers the version -9003 is suitable.
The beam profile of the miniTA is optimized at the specified output power. The further away the laser is operated from this condition the more the beam will differ from a circular shape. The reason for this is the astigmatism of the TA chip, which depends on the operating conditions.
The laser component can be used under the absolute maximum ratings for a short period of time. For long term suage please refer to the section recommened operating conditions.
In our data sheets we specify the wavelength in vacuum.
We recommend the following procedure. 1. Gather Materials: Ensure you have the necessary cleaning tools: a lint-free wipe or a reel-based fiber optic cleaner (such as a cassette cleaner), 99% isopropyl alcohol (IPA), and a fiber inspection microscope if available. 2. Power Off Equipment: Disconnect the fiber from any equipment and ensure the laser source is powered off to avoid damage to your eyes. 3. Inspect the Connector: Use a fiber optic inspection microscope to check for dirt, debris, or scratches on the ferrule end-face. If the fiber is clean, no further action is needed. If dirty, proceed to cleaning. 4. Dry Cleaning Method: For lightly contaminated fibers, use a reel-based cleaner or lint-free wipe. Gently press the ferrule against the cleaning surface and swipe in one direction. 5. Wet-Dry Cleaning Method: For heavier contamination, moisten a lint-free wipe with a small amount of IPA. Lightly wipe the ferrule end-face with the wet portion, then immediately follow with a dry part of the wipe to remove any residual alcohol. 6. Re-inspect the Fiber: Use the microscope to ensure the fiber end-face is clean. If contamination remains, repeat the cleaning process. 7. Reconnect the Fiber: Once clean, reconnect the fiber to your equipment.
Within our products (if not stated otherwise) both the anode and cathode of the laser can be ground. Most customer chose the cathode as ground.
Many of our lasers achieve powers that fall into laser class 4 (according to IEC 60825-1 or FDA standard CFR 1040.10 and 1040.40) – especially if the power supply is not limited. However, these laser components can be used to build laser systems that achieve a lower laser classification by reliably controlling and limiting the laser current for all operating conditions or by restricting access to the laser radiation.
“What’s best for my spectroscopic application – a DFB or a miniECL?” – we often hear this question and would like to give you some guidance. If you’re looking for a laser with a broad mode hop free tuning range, we highly recommend a Distributed Feedback (DFB) laser diode while the miniECL is ideal when you require a very narrow linewidth. DFB lasers exhibit linear behavior in wavelength, making them ideal for applications that require stable and continuous tuning. On the other hand, if your application requires a very narrow linewidth, the miniECL is the ideal choice. While miniECLs have mode hops (as displayed in the graphic), they offer a very narrow linewidth, typically around 100 kHz. This makes them perfect for applications where precision at a specific wavelength is crucial, and a broad tuning range is not necessary. Both products are available in a 14 pin hermetically sealed butterfly package with free space output. Our DFB laser diodes in 14 pin butterfly packages are additionally available fiber-coupled and/or with integrated isolator. Moreover, TO-packages complete our DFB portfolio. Remember, DFB lasers must be selected carefully making sure its assets match to your requirements. We’re looking forward to helping you find the ideal solution! You can also check our product finder and select relevant criteria for your search.
The power stability of semiconductor lasers is significantly affected by laser temperature, laser current, and back-reflections. Variations in temperature alter the bandgap and carrier density, leading to changes in the laser’s output power and wavelength. Laser current fluctuations directly impact the number of injected carriers, causing power instability. Additionally, back-reflections from external surfaces or optics can interfere with the laser’s cavity, introducing feedback that disturbs the lasing process, resulting in intensity noise or even mode hopping. Maintaining stable temperature, precise current control, and minimizing back-reflections are essential for ensuring consistent power output in semiconductor lasers.

Naturally, the benefits vary from job to job, but EAGLEYARD is valued by all employees across the various departments for its flexibility and as a family-friendly employer. We offer mobile working where the tasks allow it and have a flexitime model with core working hours. Many employees work part-time at EAGLEYARD, but can increase their hours to full-time if necessary. Every full-time employee has 30 days‘ holiday entitlement, plus two additional days’ holiday on 24th and 31st December and further daysoff from the age of 60. We try to accommodate all holiday requests, especially during holiday periods. Three weeks’ holiday in a row during the summer holidays is not unusual. We also counteract inflation with regular salary adjustments at the end of the financial year and pay voluntary year-end bonuses in the event of a positive annual result. We promote your professional and personal development through internal and external certified workshops and training courses. We make your start, including induction, easier with an induction plan, various training courses and an onboarding day where all departments introduce themselves. To speed up integration into the team, we organise various team events such as barbecues, paddling, table tennis tournaments, company relay races and restaurant visits throughout the year. Not only the team spirit, but also the health of our EAGLES is strengthened by a one-hour active break once a week. Of course, we also provide free drinks and fruit baskets at regular intervals. EAGLEYARD employees also receive discounts and offers of up to 50 % from various providers, both offline and online. The innovation location Adlershof itself offers relevant networking opportunities with institutes and industry partners, has good public transport connections and a wide range of shopping and dining options, from inexpensive canteens to good Italian restaurants with a view of the Teltow Canal. Even if you’re travelling by car, there are always nearby parking options in the side streets and backyard. In the team, even the working student is on first-name terms with the CEO, we have no dress code and define ourselves through transparent communication, open doors and short decision-making processes.
The induction programme differs from department to department and starting time. However, every new team member, regardless of whether they are a permanent employee, intern or student, should receive a good overview of the company, the location and the individual departments as standard in order to quickly gain an overview of their own area of responsibility and promote collaborative thinking. For this reason, an individual induction plan is drawn up for each new onboarding candidate. Your personal buddy is responsible for the creation. Progress is checked at regular intervals by the team leads. On the start day, in addition to the bureaucratic formalities, safety training will take place and the HR department will provide you with the most important information about everyday life at EAGLEYARD. Later in the day, you will be introduced to all the EAGLES present and familiarised with all the premises.
Our onboarding day takes place once every three months. At this event, all departments are represented by one or two representatives. The tasks, team members, special features and current challenges in the department are discussed. In the first six months, you will have one or two feedback meetings with your team lead to discuss your progress, performance, etc.
You can’t really say that in general terms. If you find an advertised position with us interesting, we would be pleased if you would include not only a CV, but also a letter of motivation and relevant (work) references with your application documents. We also often ask for references. For applications from working students, we also like to see the current enrolment certificate and course description. If you have applied directly via our applicant management portal, you will immediately receive an automated confirmation of receipt. For unsolicited applications via jobs[at]toptica-eagleyard.com, you will only receive confirmation of receipt after your application has been added to the applicant management portal. In this case, you will need to confirm our privacy policy via a link. Only then will we proceed with your application. After your documents have been reviewed by the HR and specialist department, you will either be invited to an initial interview via video call or to a personal interview on site if you are suitable. At least one member of the specialist department and, as a rule, one member of the HR department will be present at each interview. In the initial interviews, we primarily want to get to know the person behind the CV. As a rule, there will be a second meeting on site to give you an insight into our premises, introduce you to your future team and let you try out some work. This can take the form of a small design task after prior instruction; it can be a presentation of your thesis/doctoral thesis or even the operation of a microscope, to name a few examples. For special positions, especially those with management responsibility, our CEO Claus will also want to get to know you. If everything is right from both sides, we will send you an initial draft contract. If you have no requests for changes, you can come in person to sign the contract or it will be sent to you by post. Some positions are only advertised for a certain period of time, which is why it may be the case that you have only recently applied and you are rejected despite being suitable because we have either already received enough suitable applications for this position or have already hired someone. As a rule, we will then invite you to join our talent pool so that we can contact you for new interesting positions. Unless otherwise agreed, your application will be deleted from our system after six months. So please don’t be confused if we can no longer recognise you when you reapply.
There really is no such thing as a typical EAGLEYARD employee. We employ people of all ages, from career starters to those about to retire. We often employ people in production who have completed vocational training, but also academics. In our wafer fabrication and research and development department, there are even some PhD graduates among the academics. Due to our core expertise and our industry focus, we have a clear STEM focus when hiring, even though we naturally have an administrative apparatus like any company, where many employees have a business or commercial degree.Most academics who work at EAGLEYARD have a degree in physics, engineering or, less frequently, computer science. Of course, we have also hired career changers in the past, where we took a closer look at the soft skills of the applicants. However, this is not feasible for all positions. On average, our employees have been with the company for five years and we have already celebrated 20 years with many of them.
If you can’t find a suitable position among those currently advertised, there’s no harm in sending an unsolicited application via jobs[at]toptica-eagleyard.com. Please always state which positions you could generally imagine, what interests you, what your approximate salary expectations are and until when you will be available to the labour market. Sometimes positions are not even advertised yet and you make it easier for us to find staff. However, please don’t be disappointed if we don’t have a suitable position for you at that time. If you have an attractive profile and convincing application documents, we will invite you to join our talent pool via a link so that we can contact you about new vacancies that suit you.
