高功率激光系统中B积分的研究

通过对非线性薛定谔方程的求解,数值模拟了高功率激光系统中钕玻璃的B积分传输规律,并理论分析了B积分对光脉冲的波形和频谱的影响,详细介绍了几种消除B积分影响的方法。这对高功率激光系统中光放大有一定指导意义。

Through solving the nonlinear Schrdinger equation,the propagation variation of B integral of Nd:glass in high power laser system is numerically simulated.The effect of B integral on the wave shape and the spectrum of the optical pulse is theoretically analyzed.Several methods of removing B integral effects are introduced in detail.This is important for optical amplification in high power laser system.
