Abstract

It has been found that excimer laser radiation, at intensities of 108-109 W cm-2 irradiating metal targets in air, can result in both surface roughening and oxidation. The increased absorptivity E(A,T), as a result of the surface modification, has been measured directly. Using a calorimetric technique, the measured absorptivity at 10.6μm, indicates that the coupling of CO2 laser radiation can be greatly enhanced with a pre-treating series of overlapping excimer pulses.
