摘　　要：实现了一种新型的非腔长匹配相干叠加脉冲锁模Ｎｄ：ＹＡＧ激光器的锁模运转。锁模脉冲宽度为６０ｐｓ．给出该种新型锁模激光器的运转特性以及锁模状态与各种实验参数之间的关系。对于该种激光器的各种实验现象给出了简明清晰的物理解释。new type of mode-locking laser-non cavity length matched additive pulsemode-locking laser was realized experimentally.This new kind of laser consists ofan active mode-locking Nd:YAG laser and a nonlinear antiresonant ring as an endmirror.A semiconductor doped glass was used in the nonlinear resonant ring as anonlinear element in which the nonlinear phase shift was produced when the mode-locked light pulse propagate through it.In proper conditions stable mode lockingperformance was got with a pulse width of 60 ps which is more than three timesshorter than that from a normal active mode-locking Nd:YAG laser.The mode-locking characteristics of this laser are presented in this paper.
