This is a study of an active mode synchronization regime (mode locking) in a three-mirror semiconductor laser obtained by modulation of the laser current at the frequency of intermode beating of the external laser cavity through a feedback circuit. Under certain conditions stable active mode-locking is observed, and when the length of the external cavity is varied, corresponding tuning of the intermode beat frequency occurs. The main conditions under which this regime is attained are determined. The width of the intermode beating spectrum is found experimentally to be ~300 Hz for an intermode frequency of 300 MHz. The half width of the optical spectrum is ~4 nm.

具有互模频率反馈的有源锁模半导体激光器

这是对三镜半导体激光器中的有源模式同步机制(锁模)的研究,该三镜半导体激光器通过通过反馈电路以外部激光腔的共模跳动频率调制激光电流而获得。在某些条件下,观察到稳定的主动锁模,并且当改变外腔的长度时,会发生模式间拍频的相应调整。确定达到该制度的主要条件。对于300 MHz的模间频率,通过实验发现,模间跳动频谱的宽度约为300 Hz。光谱的一半宽度为〜4 nm。
