Theoretical analysis of the mechanisms of influence of hydrogen additions on the emission parameters of a copper vapour laser

CuBr-Ne-HBr laser with a high repetition frequency of the lasing pulses at a reduced energy deposition in the discharge

“…To this end, we performed detailed numerical simulation and experimental investigation of the CuBr−Ne−HBr laser plasma kinetics at typical pump PRFs and those increased to 1 MHz. This paper continues the works on revealing the causes for the improving effect of hydrogen and hydrogen bromide additives on the lasing and frequency characteristics of the Cu [7,8,11] and CuBr [16, 19, 23−25] lasers.…”

“…Here were used the kinetic model [19,25] developed in [7,8,11,23,24,26,27]. A system of stiff differential equations, including equations for concentrations of various active-medium agents and electron heat balance equations, was self-consistently solved using the PLASER software package [28−32].…”

MARS models of laser efficiency of copper bromide laser

“…Most results in this respect have been obtained with the help of kinetic models consisting mainly of tens and even hundreds of differential equations, describing the interactions between physical processes within the laser medium [1,4]. At the same time, in recent years, new investigation approaches have been developed based on the statistical processing of existing experiment data using specialized computer techniques and software [1,5].…”

Family of Asymptotic Solutions to the Two-Dimensional Kinetic Equation with a Nonlocal Cubic Nonlinearity

“…In our case, the germ is chosen to be real, since we seek the real solutions to (25). The pair Λ 0 t , r 2 t , where Λ 0 t is the trajectory (the time-dependent 0-dimensional manifold) x = X(t), determines the set of asymptotic solutions to Equation (25). In order to construct such solutions, we present the symmetry operators associated with the vectors a (−)…”
