28 February 2006 Saturable absorbed Er:YAG Q-switched laser with short pulse

We demonstrate passively Q switched 2% doped Er:YAG laser operation in the eyesafe region with sub 5 nsec pulse widths using Cr2+:ZnSe as a saturable absorber. A rod geometry operating in the burst mode and a micro slab geometry operating continuously are described. The micro slab geometry generates 6nsec passively Q switched pulses with over 1.5 Watt of output power and with multi kilohertz pulse repetition rates. The lasers are resonantly pumped with a 1534nm fiber laser.
