Buying Gain-switched Lasers

Top-level product category: lasers and laser amplifiers

More general product categories: pulsed lasers

Related product categories: picosecond diode lasers, Q-switched lasers

Gain-switched lasers can produce short optical pulses by rapidly modulating the gain in the laser medium. For example, gain-switched laser diodes are suitable for generating picosecond pulses with a flexible repetition rate. These lasers are used in applications requiring precise timing and high peak power, such as time-resolved spectroscopy and LIDAR.

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.

Read our article on best practices for purchasing.

1. Understand the technical background

It is important to sufficiently understand the technology before buying.

Use the comprehensive resources of RP Photonics:

If you need personal help, contact RP Photonics to get technical consultancy.

2. Define your requirements

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

We recommend that 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 gain-switched lasers. 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.

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

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 gain-switched 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.

gain-switched lasers

Gain-switched diode lasers of the PICOPOWER-LD series from ALPHALAS with pulses < 12 ps and peak power > 2 W at specific wavelengths offer a cost-saving alternative to mode-locked DPSS lasers. Exchangeable laser heads with wavelengths from 375 to 2200 nm offer greatest flexibility. Simultaneous multichannel operation at a number of wavelengths is also available. External TTL trigger and TTL sync output are standard features. Picosecond pulses are generated with repetition rates from single-shot to 100 MHz. Options like fiber coupling, variable amplitude, CW mode, temperature tuning of the wavelength and single-frequency are available on request for most wavelengths. All models generate a single transverse mode laser beam. Applications include fluorescence lifetime measurements, pump-probe experiments, laser seeding, optical tomography, time-correlated single photon counting (TCSPC).

gain-switched lasers

Thorlabs’ GSL Series gain-switched lasers provide picosecond, nanosecond, and continuous wave operation in compact, fiber-coupled, turnkey sources. Gain-switched pulse generation with adjustable pulse widths and repetition rates up to 200 MHz make these lasers suitable for high-speed imaging, fluorescence lifetime measurements, and impulse testing. GSL series lasers are also ideal seed sources for additional amplification using our range of fiber-based amplifiers.
