Abstract
It has been established, that the surface destruction has 3 stages: breakdown origin (the distance is 3 - 5 mm from the surface timed up to 1 microsecond(s) regarding leading edge of laser pulse); evaporation (timed for 3 - 5 microsecond(s) ); interaction of the adsorbents with plasma torch and laser radiation, heating and cracking under the influence of UF plasma radiation.
