作为腔内脉冲能量调制源的固有Q开关，即，不想要的振幅噪声仍然是一个具有挑战性的任务，以便根据不同的商业应用制造单片锁模半导体激光器。本文介绍了在40 GHz锁模多量子阱激光器中，量子阱数目对Q开关发生和抑制的影响的实验研究结果。改进后的锁模激光器输出的短光脉冲（~ 1.6ps）具有很低的幅度噪声（1%-2%）和定时抖动（50- 100 fs）。
Inherent Q switching as a source of intracavity pulse energy modulations, i.e., unwanted amplitude noise, is still a challenging task in order to fabricate monolithic mode-locked semiconductor lasers in view of different commercial applications. In this letter, the results of experimental investigations on the influence of the quantum well number on the occurrence and suppression of Q switching in 40GHz mode-locked multiple quantum well lasers are presented. Improved mode-locked lasers emit short optical pulses (⩽1.6ps) with very low amplitude noise (1%–2%) and timing jitter (50–100fs).
