摘要
本文采用速率方程讨论了双区共腔双稳激光器获得超短光脉冲的方法及特点。结果表明,采用一般的电脉冲触发,利用双稳激光器的Q开关长延时特性,能够获得质量较高的超短光脉冲。
Based on the rate equations,the analysis of the transient behavior which Ieads to a methodfor obtaining ultra-narrow light pulse is given.It shows that owing to strong Q-switch andlong delay effects in the device, a better quality ultsa-narrow light pulse under electric currentinjection can easily be achieved in comparison with that in a normal DH laser.
