We report self-pulsation in an erbium-doped silica toroidal microcavity laser coupled to a tapered fiber and investigate the effects of pump power and taper-cavity coupling condition on the dynamic behaviors of the pulse train. The microcavity is pumped at 1444.8 nm, and lasing occurs at 1560.2 nm with a threshold of 12 microW. Experimental results are interpreted within the framework of ion-pair induced self-quenching model.
我们报告了一种掺铒二氧化硅环形微腔激光器与锥形光纤耦合后的自脉冲现象,并研究了泵浦功率和锥形腔耦合条件对脉冲串动态行为的影响。微腔在 1444.8nm 处被泵浦,在 1560.2nm 处激光发射,阈值为 12μW。实验结果在离子对诱导自猝灭模型的框架内进行了解释。
