Analysis of gasdynamic regimes of interaction of CO[sub 2] laser radiation with targets in air at normal and reduced density
The feasibility of using high-power CO[sub 2] lasers [1,2] for machining, development of a laser-propelled jet engine, atmosphere sounding, plasma heating, and other applications is the subject of much research into the physics of the interaction of IR laser emission with gases and condensed media. This research was initiated following the observation of low-threshold optical breakdown of gases near solid surface [3-5], and is extensively reviewed, e.g., in [6,7]. Characteristic features of the action of high-power laser pulses on gaseous targets are evaporation and ionization of the target material, gasdynamic expansion of the erosion plasma [8], and entainment of the ambient gas in the laser-emission absorption wave [9].
