Surface-to-Bulk Optical Absorption on Uncoated Sapphire and Zinc Selenide Using Photoacoustic Chopping Frequency Studies

Source

Experimental photoacoustic (PA) signal amplitude and phase angle data were taken on uncoated CVD ZnSe at 10.6 μm and on (0001) oriented single crystal sapphire (Al2O3) at 1.3 μm. The data were interpreted using the Rosencwaig-Gersho theory, the McDonald-Wetsel composite-piston model and the Bennett-Forman theory. A modified version of the Rosencwaig-Gersho theory was developed which explicitly incorporates surface absorption. It was also applied to these cases. Comparisons are made with some multithickness sample studies on related materials.
