Photoacoustic chopping frequency studies on ZnSe laser windows using a CO_2 laser
Abstract
Experimental photoacoustic spectroscopy (PAS) amplitude and phase results on an AR-coated ZnSe laser window were obtained at 10.6 microns as a function of chopping frequency. Theoretical calculations related to this situation were performed using the Bennett-Forman, Rosencwaig-Gersho, and two layer Rosencwaig-Gersho theories.
