Abstract:

The effect of 10.6 micrometer pulsed laser radiation on large grain ZnSe is examined with respect to the local crystallography of the material. In particular, the presence of twin boundaries, a common defect in II-VI materials, is shown to have very little effect on the damage threshold. Damage effects were monitored by Nomarski interference contrast microscopy, electron microscopy and x-ray topography.
