Significant oscillations of the spectral distribution of the idler pulses in the optical parametric amplification of chirped laser pulse have been observed experimentally. On the base of the obtained simple analytical solution we have showed that such oscillations and an asymmetry of the spectral and temporal distributions of the intensities of the signal and the idler were caused by small variations in the parameters of the initial idler in comparison with the signal one. Conditions for distortion of the shape of the temporal and spectral distributions of the amplified compressed output pulses in a multi-stage laser with optical parametric chirped pulse amplification have been determined.
