Abstract

This paper describes gasdynamic regimes of high-power pulsed laser interaction with solid targets in the ambient air of normal and reduced densities in the moderate intensity range 0.1 - 1000 MW/cm², typical four numerous laser applications. The experiments have been performed with a set of CO, CO₂ and KrF laser installations with output energy up to 100 J and pulse durations of 0.1 - 200 microsecond(s) . Supersonic erosion jet formation during target evaporation as well as different types of laser- supported absorption waves, i.e. laser-supported detonation waves, subsonic and supersonic radiation waves have been identified for the variety of radiation wavelength 0.25, 5.0 - 5.6, 10.6 (9.6) micrometer. The results on the gasdynamic regimes determination, being obtained for sufficiently big irradiated spots approximately 1 cm, might be extended for much higher energies available for these types of lasers in large-scale environments.
