摘要
从非线性薛定谔方程出发,运用分步傅立叶变换(FFT)算法,研究了啁啾脉冲激光在钛宝石放大介质中的传输和放大特性,详细讨论了放大介质的增益饱和与增益窄化效应,以及光束的波前位相畸变对输出脉冲时空特性的影响。
Using nonlinear Schrdinger equation,the propagation and amplification properties of chirped-pulse beams through the Ti:sapphire amplified medium were studied by split-step Fourier method.The gain-saturation and gain-narrowing effects of amplified medium have been discussed in detail.The influence of the phase perturbation on the spatial and temporal characteristics of the output pulse beams has been also analyzed.
