摘要
本文建立了一个不涉及具体光腔结构的双波长固体飞秒激光器模型,分析了群达弥散(GVD)、自相位调制(SPM)、交叉耦合、损耗调制和增益放大的动态平衡过程.从场算符的定义出发,导出了双波长飞秒激光器的量子锁模方程组,并且将该量子销模方程组化为经典锁模方程组.结果表明,该方程组和非线性薛定谔方程有着类似的结构,方程组存在稳定的脉冲解,因而从理论上证明了双波长飞秒激光器可以实现双波长同时锁模.
In this paper,a quantum mode--locking equation has been established on the basis of a newdual--wavelength fs laser model,which discribes the shaping for dual--wavelength fs laser pulses. Thebalance among group velocity dispersion (GVD),self--phase modulation(SPM ),cross coupling,gain andloss has been analysed. The results show there are the stable pulse solutions to the quantum modelocking equation. A dual--wavelength fs laser can be mode--locked theoretically.
