| 摘 要： | 研究了增益饱和在啁啾脉冲放大中的影响，发现由于增益饱和在存在，压缩后脉冲的信噪比会下降，而且展宽器附加的色散也会降低输出的信噪比，这种降低对应着一定的光谱畸变。通过对展宽／压缩器作用的分析，提示了啁啾脉冲放大中光谱与光强的内在联系，提出利用非共振放大来修正光谱畸变提高放大压缩后的信噪比。

| Abstract: | The effects of gain saturation (GS) in chirped pulse amplification are studied in this paper. It is found that the compressed signal to noise ratio (SNR) may decrease due to GS and the dispersion added by stretcher. The decreasing corresponds to distortion in frequency domain. The analysis on the stretcher/compressor shows the internal relation between spectroscopy and time intensity. It is advised that frequency mismatch may be used to modify the spectral shape and increase SNR. |
