Abstract
A cycle of experimental investigations was carried out on radiation-gasdynamic processes that evolve when high-power (∿1.5 GW) pulses from an electron-beamcontrolled CO2 laser act on a target in air or in inert gases at pressures 0.1–760 torr and flux densities 5·106 to 5·108 W/cm2. It is shown that at pressures above several torr a laser-radiation absorption wave is produced in the gas surrounding the target and determines the evolution of the interaction. The laser-stimulated-detonation, subsonic, and supersonic radiative regimes of absorption-wave propagation in gases are investigated under conditions of planar one-dimensional geometry of the experiment and at large (up to 20 cm2) area of the irradiated spot.
