Abstract

Temporal and spatial evolution of shock waves generated during drilling processes of optical materials by a high repetition rate copper vapor laser were investigated by means of a CW probe beam deflection technique. Experimental results of the cinematic behavior and of the air density distribution of the shock wave were compared to respect a theoretical model of shock wave expansion providing also quantitative information on the main physical functions associated to laser-induced acoustic phenomena.
