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 a 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 in the cross-over.
