Abstract

Abstract

The dispersions resulted from practical stretcher and compressor in optical parametric chirped pulse amplify system are studied by ray-tracing method, and the pulse amplify is numerically simulated using Runge-Kutta method. The effects of misalignment of grating planes and grooves, signal intensity and pump intensity are discussed. The simulations show that misalignment of gating planes leads to pulse broadening. When the angle of grating groove is 0.8°, the pulse width is the narrowest in the case of group delay dispersion. When the angle of grating groove is 1°, the pulse width is the narrowest in the case of three-order dispersion.
