Where to Buy 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.

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).
