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 or DFB laser diode) can reach high power in nanosecond pulse regime up to 500 mW. These 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.
