Abstract

Kinetics of luminescence flashes (LF) accompanying optical breakdown development in volume of alkali halides crystals under the action of carbon-dioxide laser radiation pulses with intensities near by the threshold of LF appearance (approximately 10 MW/cm²) has been studied. LF shape and intensity have been investigate under the action of the first and subsequent pulses on the same place of the specimen. It has been observed that LF consist of large numbers of more or less resolved spikes with duration at least approximately 100 ns (or less) which has been determined with time resolution of the used apparatus. It has been shown that peculiarities of observed LF kinetics cannot be explained on the base of conclusion about their thermal nature and do not contradict conception of tiboluminescence and its irregularities. Triboluminescence is a result of crystal fracture (in crystal areas, surrounding absorbing inhomogeneities) under the action of thermal stresses caused by absorbing inhomogeneities temperature growth.
