Abstract

A critical factor in the performance of high power industrial CO2 lasers is the substrate material used for optical components in the laser and beam delivery system. The choices for transmissive optics such as lenses and output couplers can be narrowed down to GaAs or ZnSe with low absorbing coatings, however, determining which one of these two materials will work best in a particular application can be difficult and in some cases ambiguous. This paper compares ZnSe and GaAs as used in high power laser applications by use of thermal finite element analysis, laser calorimetry data, and a relative figure of merit function.
