Theoretical study on pulse properties of optical parametric chirped pulse amplification
In this paper, the nonlinear coupled equations are presented and the pulse properties of an optical parametric chirped pulse amplification(OPCPA) system are studied. By numerical simulation, it is discovered that signal temporal profiles and spectral profiles broaden after saturated amplification, but the pulse and spectra broadening don't affect the S/N coefficient of the compressed pulse. Analysis and discussions are also given.
