Abstract
Experiments were performed on Q switching of erbium lasers at 3 μm with an acoustooptical modulator. Different laser crystals of YAG:Er and YSGG:Cr:Er have been investigated. The highest fraction of single pulse Q -switch energy to free-running mode energy was 1%. Pulse durations of 50 ns were obtained. Multiple switching with up to 14 Q -switch peaks per flashlamp pulse could be generated, containing up to 19% of the energy of the free-running mode
