Abstract
A technique for precision rapid nondestructive monitoring of the dopant behavior in zinc chalcogenide–based laser media is reported. Results suggest that it is possible to determine the concentration profiles of Fe2+ and Cr2+ dopant ions in zinc chalcogenide by IR spectroscopy combined with an IR microscope in the concentration rage 5 × 1017–2.5 × 1020 atoms/cm3 with a spatial resolution of several micrometers. The diffusion profiles of dopants have been taken for zinc chalcogenide codoped by several impurities.
