Numerical simulation evolution of radiation spectra in the XeF(C-A) amplifier THL-100 laser system
Using numerical simulation methods it was studied the evolution of the spectral characteristics of frequency-modulated radiation with a duration of 250 ps and an energy of 2 mJ and a central wavelength of l = 475 nm in the XeF(C-A) amplifier of the THL-100 laser system. The laws of the deformation of the spectra and spectral energy density of laser radiation was investigated. When the energy of the VUV amplifier pump radiation is 270 J, the maximum spectral energy density of the output radiation reaches 0.92 and 0.91 J×nm-1 in the positive and negative chirp modes, respectively. It is shown that in the gain saturation mode, the radiation wavelength with the maximum spectral energy density increases on a positive chirp: from 475 to 477.8 nm, and on a negative chirp decreases: from 475 to 472.5 nm.
