Abstract
An algorithm for numerical simulation of time–frequency energy distribution of chirped Gaussian laser beams during amplification is proposed. The algorithm is based on a time–frequency description of laser radiation by the Wigner distribution function and the concept of a physical spectrum, which allows one to use the photon transfer equation for modeling the evolution of space, energy, and spectra characteristics of laser radiation. A comparison of the numerical simulation results and experimental measurements of laser radiation characteristics in a XeF(C-A) gas amplifier of a THL-100 hybrid laser system confirmed the applicability of the proposed model.
