Paper Abstract

Heating effects in laser processing of metals are greatly influenced by the metal reflectivity, R and by the coupling coefficient ε = 1 - R. In this paper we discuss several methods by which ε may be measured, including a simple calorimetric technique that yields ε(T) for highly reflecting metals. This technique has been applied to measure E(T) for a variety of metals for CO2 and excimer laser radiation.
