摘要：
An investigation was made of the influence of nanosecond ruby laser radiation pulses with a power density below the thresholds of melting, sublimation, and damage on the dislocation density, as well as on electrical and photoelectric properties of p-type CdTe crystals and on the luminescence emitted from them. A reduction in the conductivity of these crystals after laser irradiation was accompanied by a reduction in the photocurrent and in the luminescence intensity, and was due to multiplication of dislocations as well as migration of Li(Cd) and Na(Cd) acceptors from the bulk to dislocations.
