摘要

克尔透镜锁模激光器已知适合于产生几飞秒脉冲。本文在考虑时空耦合的场包络波方程的基础上，建立了克尔透镜锁模激光器的全时空数值模型。我们详细分析了钛蓝宝石激光器的不同振荡机制。论证了系统的稳定区域、横模跳动引起的准锁态、不同类型的脉冲序列不稳定性。给出了稳定产生最短脉冲所需的色散、腔臂长度和往返增益。

The dynamics of few femtosecond pulse in a Kerr-lens mode-locked laser from full space-time domain simulations

The Kerr-lens mode locking lasers is known suitable for generation of few femtoseconds pulses. In this paper, we have developed full spatio-temporal numerical model of Kerr-lens mode-locked laser based on the wave equation for field envelope taking into account the space-temporal coupling. We present a detailed analysis of different regimes of oscillations of Ti:Sapphire laser. The stability region, quasilocking regimes caused by transverse mode beating, different kind of pulse train instabilities are demonstrated. The dispersion, cavity arm lengths, round-trip gain necessary for stable producing of shortest pulses are presented.
