摘要
本文通过建立一合理的锁模模型,采用数值算法模拟了Nd:YAG主动锁模激光器脉冲的瞬态形成。发现初始的自发辐射,在腔内必须往返10 ̄5~10 ̄6次(对应时间为1ms左右),才进入稳定的锁模状态。实验中,我们采用一简单的方法测出了锁模脉冲的这一稳态建立时间,而且与理论计算结果基本相符。
By setting up a suitable active mode-locked mode,the evolution process of a instantaneous pulse is simulated with a numerical calculation method.The simula-tion results show that the primary radiation come to a stable mode-lock state only after 1~1.5ms reflections(about 1 ms ).With a simple method,the evolution time of a mode-locked pulse measured experimentally.This experimental result is consistent with theory calculation basically.
