Abstract

The measurement of small absorption coefficients in transparent infrared materials is currently a subject of considerable interest. The practical motivation for the work arises from the need for evaluating materials for high power laser windows but there is also a more fundamental interest in developing an understanding of intrinsic and extrinsic optical absorption mechanisms which limit material performance. A considerable number of measurement techniques [1] have been developed which utilize a variety of physical indicators for measuring low optical absorption.
