Simulation of time–frequency characteristics of a chirped laser beam in a XeF(C-A) amplifier of a THL-100 laser system

Applied Optics (2023)

A. G. Yastremskii S. A. Yampolskaya В. Ф. Лосев Yu. N. Panchenko А. V. Puchikin

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.

Influence of the input radiation pulse characteristics on the parameters of a XeF(C – A) amplifier in a THL-100 laser system

Quantum Electronics (2016)

A. G. Yastremskii N. G. Ivanov В. Ф. Лосев

We report the results of experimental and theoretical investigations on the influence of spatial and energy parameters of input radiation with a pulse duration of on output characteristics of a XeF(C – A) amplifier in a visible-range, multi-terawatt THL-100 laser system. Dynamics of the energy density radial distribution for laser radiation passing through the amplifier is studied. Results of numerical simulation are presented for amplification of laser beams with Gaussian and super-Gaussian radial energy density distributions. It is shown that the laser energy of obtained experimentally is not the limiting value. According to calculations, the output energy of the amplifier with such mirror configuration may reach , which in the case of a pulse compressed down to corresponds to the radiation power of .

Potential of Sub-THz-Wave Generation in Li2B4O7 Nonlinear Crystal at Room and Cryogenic Temperatures

Crystals (2021)

Dmitry M. Ezhov Snezhana A. Turgeneva Н. А. Николаев А. А. Мамрашев Sergey L. Mikerin

Due to their high optical damage threshold, borate crystals can be used for the efficient nonlinear down-conversion of terawatt laser radiation into the terahertz (THz) frequency range of the electromagnetic spectrum. In this work, we carried out a thorough study of the terahertz optical properties of the lithium tetraborate crystal (Li2B4O7; LB4) at 295 and 77 K. Approximating the terahertz refractive index in the form of Sellmeier’s equations, we assessed the possibility of converting the radiation of widespread high-power laser sources with wavelengths of 1064 and 800 nm, as well as their second and third harmonics, into the THz range. It was found that four out of eight types of three-wave mixing processes are possible. The conditions for collinear phase matching were fulfilled only for the o − e → o type of interaction, while cooling the crystal to 77 K did not practically affect the phase-matching curves. However, a noticeable increase of birefringence in the THz range with cooling (from 0.12 to 0.16) led to an increase in the coherence length for o − o → e and e − e → e types of interaction, which are potentially attractive for the down-conversion of ultrashort laser pulses.
