Impurity Induced Absorption in Potassium Bromide Crystals for Infrared Optical Applications
Abstract
Investigations of the optical properties of 'pure' and doped alkali halide crystals between 9 micrometers and 11 micrometers were carried out using CO2 lasers and Michelson interferometers. The extrinsic absorption due to residual impurities in purified alkali halides was used to categorize the optical quality of the crystals. The absorption in doped crystals was studied both interferometrically from which the internal vibrational modes of the molecular impurities were identified and by means of saturation spectroscopy from which excited-state lifetimes of molecular vibrations were determined.
