TIME-DOMAIN ANALYSIS OF THE MODE-LOCKED PRO-CESS BASED ON A NOVEL NONLINEAR COUPLED CAVITY

系统地研究了用带有非线性倍频晶体的附加耦合腔来压窄激光光脉冲的动力学作用过程，报道了该锁模激光系统在瞬态平衡时输出脉冲宽度的具体表达式；另外，通过数值分析计算，给出了该系统锁模激光输出特性优于单腔情形的原因。

Dynamic processes of the modelocked laser based on a auxiliary coupled cavitycontaining a nonlinear frequency-doubling crystal has been systematically studied inthis paper.And,the specific formulas of the output pulse width of this modelockedlaser in instantaneously dynamic equilibrium are given,Moreover,the results of nu-merical analysis and calculation show that its modelocking output properties are su-perior to that of the laser modelocked by an intracavity frequency-doubling crystal.
