The Surface Absorption of Unpainted Alloys at 10.6 Microns.
Abstract
The surface absorption of 10.6-micrometer radiation was measured for alloys of aluminum, magnesium, stainless steel, and titanium. Coupling coefficient data were taken from one- and two-dimensional heat flow experiments where there were a wide range of heating rates and temperatures achieved. The relative importance of some experimental variables in laser effects experiments such as beam intensity profile, aiming error, sample-to-sample surface variations, etc., have been determined. For the samples of titanium and stainless steel brought through their melting points no changes in coupling due to temperature or oxide formation were resolved. A dependence of coupling coefficient on beam intensity was observed for the stainless steel alloy. (Author)
