标题： Self-Pulsating Semiconductor Lasers: Theory and Experiment

摘要： 我们报告了半导体CD激光器自脉动频率与泵浦电流依赖关系的详细测量。 在此依赖关系中发现了一个明显的拐点，并使用速率方程模型进行解释。 该拐点表示自脉动处于弱持续弛豫振荡区域和Q开关发生区域之间的转换。 模拟表明，自发辐射噪声在交叉过程中起着关键作用。 显示英文摘要

摘要： We report detailed measurements of the pump-current dependency of the self-pulsating frequency of semiconductor CD lasers. A distinct kink in this dependence is found and explained using rate-equation model. The kink denotes a transition between a region where the self-pulsations are weakly sustained relaxation oscillations and a region where Q-switching takes place. Simulations show that spontaneous emission noise plays a crucial role for the cross-over.
