Description
Summary:On the basis of analysis of the results of the numerical simulation of a nonstationary gasdynamic processes and conjugate heat transfer in laser cavities of different geometries, the possibility of organization of a pulse-periodic process with definite frequency characteristics in such a cavity was determined depending on the initial pressure of the gas in the cavity, the density of the energy supplied to it, the composition of the gas mixture in the cavity, and the thickness of its walls. The state of the system comprising a gas cavity and its shell under the action of a single laser pulse and a series of laser pulses was simulated.
