Numerical modeling of active media chemical composition dynamic change in sealed-off pulsed periodical TEA-CO2 lasers

摘要

Abstract: Algorithms were researched and evaluated for the active media chemical composition dynamic change in sealed-off pulsed-periodical TEA-carbon-dioxide lasers. These algorithms include behavior of up to 64 charged and neutral compounds. Also reported are the results of simulation of the transition to a quasi-equilibrium state of basic neutral compounds (carbon- dioxide, CO, O, O$-2$/, O$-3$/, N$-2$/, N, NO, NO$-2$/, NO$-3$/, N$-2$/O) in carbon- dioxide-laser mixtures of atmosphere pressure at the volume discharge of energy density W equals 0.1 to 0.5 J$+*$/cm$+$MIN@3$/ excitation with the pulses repetition rate F equals 10$+2$/ - 10$+4$/ Hz. !12
