Investigation on the Absorptance of Stainless Steel Targets Irradiated by a TEA-CO2 Laser,

Abstract

A methodology has been developed to measure the absorptance (alpha) of metal targets irradiated by a TEA-CO2 laser. The approach allows dynamic measurements of the behavior of alpha when a laser beam is the sole heating source involved. Temperature-dependent thermophysical properties are considered in the reduction of the experimental data. It is shown that oxidation increases drastically the coupling of energy to the target above a threshold temperature which is a function of the type of material used and the environment into which the test is made.
