Abstract

Abstract

With ray tracing analysis method, a theoretical analysis of wavefront aberration is made in pulse compression gratings. A model made up of pulse compression grating pair with wavefront aberration is applied to calculate the effect of the wavefront aberration on pulse compression. The preliminary conclusion shows that the maximum rate of compression ratio changes is about 2% and the change rate is less when the peak-to-valley value of wavefront aberration is less than a quarter of wavelength and incident angle is properly．
