12 mJ 10 Hz Diode Pumped A/O Q-switched Yb:Er:Glass Laser

An eye-safe Yb:Er:glass laser with a repetition rate 10 Hz was developed. The device was a diode pumped Yb:Er:glass laser Q-switched by an acousto-optic gate producing 12 mJ energy and 20 ns FHWH duration pulses of 1.54 um radiation. The laser rod and laser diodes are cooled by a thermoelectric module. The laser head dimension were 180×80×80 mm³.
