Part of the Materials Science Research book series (MSR, volume 5)


One important factor limiting the advance of high power laser technology is the failure of laser materials due to optically induced damage. Examples of surface damage, extrinsic damage produced by inclusions, and intrinsic hulk damage (beam trapping) are presented. A model to treat metallic inclusions which absorb an appreciable amount of incident laser radiation in glass laser rods is formulated and used to estimate thermal stresses and changes in refractive indices due to the thermal stress field. The feasibility of optical techniques to detect incipient damage sites also is discussed.
