On photovoltaic nature photorefraction in KD~*P at the room temperature and 2w-generation phase synchronism shift in it

摘要

The accounted by us in dislocational model a room-temperature photorefractive effect due to failure of dislocations to new fastening points. It gives to initiation of electrical polarized areas in light heating zones in KD~*P crystal. In this investigation pulse currents generated in the crystal at its pulsing irradiation have been detected
