摘要 为研究群时延色散与自相位调制对被动锁模固体激光器输出脉冲的影响,数值求解了描述激光器动力学的Haus主方程。采用饱和吸收体的快饱和模型,分析了群时延色散与自相位调制相互平衡和二者共同作用时的两种条件下,脉冲在腔内的演化。结果表明,后一种情况可以使固体激光器产生更短更稳定的光脉冲。 In order to discuss the effects of group delay dispers ion (GDD) and self-phase modulation (SPM) on the pulses generated from passivel y mode-locking solid-state laser,the Haus master equation which described the femtosecond pulse solid laser dynamics was solved numerically.Adopting the fast saturable absorber model,the pulse evolutions were analyzed in two conditions ,one of which was the balance between GDD and SPM,and the other was the effect of GDD and SPM together.The conclusion shows shorter and steadier pulse can be produced by solid-state laser in the latter condition.
