摘要：
A simple model is presented to analyze the spectral shape and bandwidth dependence of the pulse contrast and compressed pulse width in the chirped pulse amplification. The parameters of the 30 fs laser system are demonstrated as examples. Comparing with Top hat, Lorentzian, Sech(2), Gaussian, 2nd Super Gaussian and 10th Super Gaussian spectral pulse shape, the 2nd Super Gaussian spectral pulse shape can obtain better contrast in the case of less spectral bottom width. Those results are helpful to find an optimized spectral shape in the chirped pulse amplification. (C) 2013 Elsevier GmbH. All rights reserved.
