Paper Abstract

A method is proposed for recording and development of optical information on photothermoplastic (PT) media. The method is based on using radiation of an YAG:Nd laser. Specialized lasers and recording devices on their basis have been developed which ensure obtaining nanosecond (about 30 ns) radiation pulses in the visible range ((lambda) equals 0.532 micrometers ) to be used for exposure in the presence of infra-red background radiation ((lambda) equals 1.064 micrometers ) of quasi-stationary lasing of large duration which is used for thermal processing of the medium. The recording unit proposed makes it possible to realize a multi- stage PT recording process including exposure and thermal processing of the medium by one laser shot.
