| 摘 要： | 将液晶空间光调制器用于超高斯种子脉冲光谱整形，重点分析了调制器参数对压缩脉冲信噪比的影响，以此为依据对其结构参数进行优化设计，以降低其影响。对整形、放大及压缩过程的理论模拟表明:应用液晶空间光调制器进行光谱整形时，能够有效克服钕玻璃啁啾脉冲放大系统的非线性效应，在放大器输出端保持原始光谱宽度，但液晶空间光调制器对光谱的调制作用使压缩脉冲信噪比降低。

| Abstract: | The liquid crystal spatial light modulator(LCSLM) was used to shape the super-Gaussian seed pulse. The simulation results of the shaping, amplification and compression processes, indicate that the spectrum shaped by liquial crystal spatial light modu letar eliminates the nonlinear effect of Nd: glass chirped pulse amplification system, the spectral width of the amplified pulse is as the same as that of the initial one. But the structural parameters of the device show great impact on the signal noise ratio of the compressed pulse. We analyzed the relationship between structural parameters and signal noise ratio and the results are useful for application and optimum design of such device. |
