Antiphase Q-switch dynamics in a multimode solid-state laser with saturable absorber

Antiphase Q-switch dynamics in a multimode solid-state laser with saturable absorber is investigated both experimentally and theoretically. The system under study is a large cavity, longitudinally pumped Nd:YAG laser with Cr4+ :YAG as saturable absorber. Asymmetric two-mode operation was found for a...
