Interaction of High-Energy Pulsed CO2 Laser with Material
The interaction of a high-power laser on material induces various phenomena which depend mainly on the nature of the material, the intensity of the laser, and the pressure of the surrounding atmosphere. In particular, when solid and liquid targets are irradiated by a CO2 laser, or when the laser beam propagates through the atmosphere, thermomechanical effects arc observed by measuring the mechanical coupling and by characterizing the plasma created above the surface of the target. The influence of the aerosol particles on the propagation of a laser beam through the atmosphere is also presented. All these effects are experimentally studied.
