摘要
本文采用有限差分方法对双波长飞秒激光器的运转特性进行了数值分析,得到了不同腔内群速弥散量下交叉锁模脉冲的数值解.结果表明,在双光束谐振腔内,由于飞秒激光的相互作用、平衡增益竞争、补偿腔内的群速弥散。
Numerical method is used to study running characteristics of dual wavelength femtosecond lasers and finite difference is used to solve cross mode locking equations.The results show two trains of mode locking pulses interact in two beam laser cavity,only the gain competition is balanced and the dispersion is compensated can the optimum running state of dual wavelength femtosecond lasers be obtained.
