Top-level product category: lasers and laser amplifiers

More general product categories: semiconductor lasers

More specific product categories: direct diode lasers, external-cavity diode lasers, fiber-coupled diode lasers

Related product categories: laser diodes, laser diode modules, laser testing equipment

Diode lasers are semiconductor lasers based on laser diodes. They have a wide range of applications, including pumping solid-state lasers, laser spectroscopy, optical metrology, and laser material processing. Their compact size, efficiency, and versatility make them indispensable in modern technology.

Making Good Purchase Decisions

RP Photonics helps you to not only to find all relevant suppliers, but also to make good purchasing decisions.

NEW: Structured Decision Process

We recommend that you apply best practice by using the following structured process: Go through the following expandable sections, complete the form and finally come to a purchase decision. You can then print that to a PDF for documenting the process.

(Various further improvements of this feature will come soon.)

1. Learn about the technology

It is important to sufficiently understand the technology before buying.

encyclopedia article

With its comprehensive resources, RP Photonics helps you to well prepare purchase decisions:

2. Define your requirements

It is important to fully understand and define your requirements before you buy.

We recommend that for your preparation and for inquiries to suppliers, you draw up a list of clear specifications according to your specific needs:

To help you, we have already listed some aspects we recommend you consider when buying diode lasers. Of course, there may be other aspects that are relevant to your specific case.

Otherwise, you will need to talk to your technical colleagues.

If you check this, the criteria will be inserted into the inquiry mail if below you use a button titled "Get quotation".

If you cannot sufficiently clarify your requirements, you may want to get technical consultancy from RP Photonics.

3. Find suppliers

We suggest three steps:

  • Below, you can find our list of suppliers for diode lasers. 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.
  • Based on the results, you can finally choose a supplier that is hopefully a good enough fit.

Selected suppliers:

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 400 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 450 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.
