Laser-induced damage measurements in CdTe and other II-VI materials.
Results of laser-induced damage measurements in CdTe and other selected II-VI materials are reported. These studies were conducted using pulsed 1.06-microm radiation from a Nd:YAG laser. The laser pulse width was varied from approximately 40 to 9000 psec (9 nsec). The laser-induced surface breakdown irradiance measured for CdTe over this pulse width range scaled as t(p)(-1/2)[t(p) is the laser pulse width (FWHM)]. This indicates that laser-induced damage in this material is due to linear absorption by a thin surface contamination layer.
