摘要
从麦克斯韦方程出发,建立了宽带高功率激光放大系统的理论模型,同时用数值方法对宽带和窄带高功率激光放大器进行了计算,讨论了增益变窄效应在放大系统中对放大脉冲的影响,从理论上提出并验证了消除由放大介质发射截面不对称对脉冲造成的畸变的方法.论文对正确设计高功率激光驱动器也具有一定指导价值.
Abstract
The theory of broad-bandwidth high power laser system is given upon Maxwell equation. By simulation, the effect of gain-narrowing in broad-bandwidth and narrow-bandwidth high power laser system is demonstrated. In addition, a method to eliminate the distortion of amplified pulse shape, resulted from Ti:Sapphire′s asymmetric cross-section of stimulated emission, is proposed and verified by computer simulation.
