Purchasing Advisor for Laser Diodes (original) (raw)
Find all you need for professional sourcing of laser diodes: 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 diodes, 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
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 diodes. 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 diodes. 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.

 AerodiodeRue François MitterrandInstitut d'Optique d'Aquitaine33400 TalenceFranceSee us at Photonics West 2026 in San Francisco, Jan. 20–22 (booth 4422)! |
⚙ hardware SHIPS TODAY: AeroDIODE offers fiber-coupled laser diodes between 520 nm and 1650 nm as stock items or associated with a CW or pulsed laser diode driver. They are compatible with our high speed nanosecond pulsed drivers or high power CW drivers (with air cooling) for the multimode high power laser diode versions. The single mode laser diodes (either Fabry–Pérot laser diode or DFB laser diode) can reach high power in nanosecond pulse regime up to 500 mW. Most turn-key diode & driver solutions are optimized for single-shot to CW performances with pulse width lengths down to 1 ns. The laser diode precision pulses are generated internally by an on-board pulse generator, or on demand from an external TTL signal. Many multimode versions are available with CW emission up to 300 W in a 200-µm core multimode fiber or up to 250 W in a 135-µm core fiber or 160 W in a 105 µm core fiber.
