| 摘 要： | 考虑到饱和增益、饱和吸收、群速弥散和自相位调制等效应对光脉冲的作用,我们给出了一个适用于飞秒脉冲激光系统的锁模方程。并且用这个方程初步地研究了同步泵浦被动锁模的染料激光器。结果表明,染料光脉冲的输出特性将极大地取决于腔内色散、S参数、饱和吸收体的浓度、腔长失谐量等因素。

| Abstract: | In this paper we present a mode-locking equation for a femtosecond dye laser system by analysing the effect of the saturable gain, saturable absorbtion, group-velocity-dispersion(GVD)and self-phase modulation(SPM)on the laser pulse. And a synchronously pumped, passively mode-locked dye laser system is studied preliminarily under the help of the equation. The result is shown that the characteristics of the output pulse are mainly determined by the intracavity dispersion, the S parameter, the concentration of the absorbe absorber and the cavity?length detuning, etc. |
