摘要
给出了描述掺钛蓝宝石激光放大器的速率方程组,通过对放大介质内反转粒子数密度和放大自发辐射的时间和空间特性的数值计算与分析,提出可通过控制泵浦光脉冲和信号光之间的时间延迟来有效地抑制放大自发辐射对放大器增益的影响。
The rate equations to describe the Tidoped sapphire amplifier were given. The temporal and spatial properties of the amplified spontaneous emission and the inversion population density in the amplified medium were studied. It is proved that, the effect of the amplified spontaneous on the gain of amplifier can be controlled by the delay time between the pump pulse and amplified pulse.
