Abstract:
We report a study of the wave structure formed by an optical discharge plasma upon the absorption of repetitively pulsed CO2 laser radiation in a supersonic (M = 1.36) air flow. Experimental data are presented on the configuration of the head shock wave and the geometry and characteristic dimensions of breakdown regions behind a laser plasma pulsating in the flow at a frequency of up to 150 kHz. The data are compared to calculation in a point explosion model with allowance for counterpressure, which makes it possible to identify the relationship between laser radiation and supersonic flow parameters that ensures quasisteady- state energy delivery and is necessary for extending the possibilities of controlling the structure of supersonic flows.
Keywords:
repetitively pulsed high-power CO2 laser, mechanical Q-switching, supersonic air flow, laser plasma, wave structure, point explosion model with allowance for counterpressure, condition of quasi-steady-state energy delivery.
