Abstract
Experimental results are presented which indicate two forms of damage in CdS irradiated by either a normalmode or Q‐switched ruby laser at power densities near 108 W/cm2. The primary damage occurs as a deep crater coaxial with the incident laser beam. This crater contains many periodic transverse fractures whose spacing suggests a phonon frequency of ∼ 100 MHz, and which is attributed to stimulated Brillouin scattering. The second site is in the region where the refracted light beam exits from the crystal.Keywords
