Purchasing advisor for laser diode drivers with supplier directory and AI-based advice; LD driver, current control, temperature control, laser safety (original) (raw)
Find all you need for professional sourcing of laser diode drivers: a comprehensive expert-curated directory of suppliers, scientific and technical background information, and an interactive AI-based tool with guidance for a structured decision process.
NEW: Not only hardware can be listed here, but also consulting, software, training on laser diode drivers, etc. – see the "offer types" below.
🌐 You appear to be visiting from North America. Many listed suppliers are based in this region, making the RP Photonics Buyer's Guide highly relevant for your needs.
Purchasing high-value photonics products is a substantial responsibility. Using a structured decision-making process and high quality supplier data helps a lot:
- Find all relevant suppliers (not limited to advertisers).
- Our interactive tool conveniently assists you in defining and applying your application-specific requirements.
Note that purchasing decisions based on just a few randomly picked suppliers and without carefully defined specifications are risky; therefore, we strongly recommend using our data and tool. See also:
- How Responsible Purchase Decisions for Expensive Goods Like Lasers Are Done
- Explanations on this purchasing tool
Go through the process:
1. Understand the technical background
It is important to sufficiently understand the technology before buying.
Use the comprehensive learning resources of RP Photonics:
If you need personal help, contact RP Photonics to get technical consultancy.
I feel that I sufficiently understand the technical background.
2. Define your requirements
It is essential to fully understand and clearly define your requirements before you purchase.
We recommend that you develop a list of clear specifications according to your specific needs, against which you can later check the suitability of found product offers:
To help you, we have already listed some aspects we recommend you consider when buying laser diode drivers. Of course, there may be other aspects that are relevant to your specific case.
This list is for your own preparation, and can later (possibly in modified form) be used for quotation requests to suppliers.
I think that I am sufficiently informed about our requirements.
Otherwise, you will need to talk to your technical colleagues.
I consider the above list of specifications to be sufficiently complete, clear and accurate.
If you cannot sufficiently clarify your requirements, you may want to get technical consultancy from RP Photonics.
Insert these criteria when creating inquiry mails to suppliers with the buttons "Get quotation".
You find these buttons in the supplier list below or under "3. Find suitable suppliers".
3. Find suitable suppliers
We suggest three steps:
- Below, you can find our list of suppliers for laser diode drivers. Use the checkboxes to mark possibly suitable suppliers.
- The selected suppliers will appear below this list, along with your list of specifications. You can then indicate which specifications they meet according to your research. (You should finalize your specifications before doing this.)
- Based on the results, you can finally choose a supplier that is hopefully a good enough fit.
Selected suppliers:
(none so far)
Decision
The most suitable supplier you found:
Comments, e.g. reasons for your choice, or things which still need to be checked:
4. Document the decision process
It is essential to document your purchasing process, not only its result (chosen supplier):
- You will find it easier next time.
- If something goes wrong, you can defend your decision by showing that you properly considered all important aspects. Or you see what needs to be done better next time.
Our interactive tool makes it easy: Fill out the form, and in the end print it to a PDF. Note that the document will show all sections (including those not currently shown on the screen), while omitting some irrelevant details such as the page navigation.

 all wavelengths. TOPTICA Photonics SELochhamer Schlag 1982166 GräfelfingGermanySee us at BiOS 2026 in San Francisco, January 17 – 18 (booth 8603, 8501) and Photonics West 2026 in San Francisco, Jan. 20–22 (booth 3603, 3501, 4713)! |
⚙ hardware Apart from a well-engineered optomechanical design and the integrated laser diode, the most important part of a tunable diode laser system is its driving electronics, which is responsible for getting the most out of a laser system. Wide mode-hop-free tuning with Littrow setups requires a well-defined interplay between piezo actuator and current driver. Drifts of the laser diode current, the temperature or the piezo voltage determine the drift of the laser frequency and the stability against mode-hopping. Noise on any of these outputs increases the laser linewidth. The digital DLC pro represents the latest stage of development of laser control electronics. Its noise and drift properties are even better than the well established and widely used preceding electronics SYS DC 110. Product-specific web page |
