Thorlabs QSL103A Q-Switched Picosecond Microchip Laser

Thorlabs has announced a passively Q-switched laser producing 500 ps pulses centred at 1030 nm. The microjoule-level pulse energies produced at kHz-repetition rates will allow for multiple applications including material processing, harmonic generation, LIDAR, photoacoustic imaging and laser-induced breakdown spectroscopy. A fibre-coupled pump source within the head produces good beam quality for efficient micromachining applications.

With a compact footprint measuring 76.2 x 136.3 mm and taps for 30 mm cage system compatibility, the QSL103A laser can be conveniently integrated into an existing system and paired with any number of Thorlabs’ cage-mounted components, including optics, motorised shutters and galvo scanners. The turnkey solution includes custom temperature control and laser drive electronics incorporated in a separate control unit for optimised stability and performance. For pulse monitoring, an SMA trigger out is provided on the laser head for clocking simultaneous events with pulse production.
