报道了一种高度可控的Tm：YAG陶瓷激光系统的光学双稳态，这归因于谐振腔稳定性的热致变化。在接近半共焦腔结构的情况下，双稳区观察到了二次激光条件，激光光束的形状被调制，激光光谱被展宽。详细讨论了温度对双稳激光运转的影响。据我们所知，这是关于Tm：YAG陶瓷激光器光学双稳效应的首次报道。
A highly controllable optical bistability in a Tm:YAG ceramic laser system is reported, which is attributed to the thermal-induced change in the stability of the resonator. The width of the bistable region can be tuned in a large scale from 0.8 W to 6.3 W. At nearly semi-confocal cavity configuration, a second lasing condition was observed in the bistable region with a modulated shape of the laser beam and a broadened laser spectrum. The influence of the temperature on the bistable laser operation was also discussed in detail. To our knowledge, this is the first report on the optical bistability effect in Tm:YAG ceramic lasers.
