An Investigation of Laser Interactions.

Abstract

This report describes work performed in a continuous program of investigations on the mechanisms by which high power pulsed CO2 laser radiation interacts with target surfaces. The experimental work has been performed using a pulsed CO2 TEA laser capable of delivering up to 1000Mw/sq cm to the target surface in a pulse of duration around 100 nanoseconds. Results described in this report include the following; The diffuse reflectivity of steel and titanium targets has been measured under varying conditions of TEA irradiation. The shock pressure coupled into metallic and potassium chloride targets by the laser-supported absorption wave has been measured interferometrically, and the results compared to catastrophic material failure in potassium chloride. The mass removal from plastic targets has been determined for various parameters of laser irradiation. (Author)
