Abstract
A Nd:YAG laser with intracavity polarization decoupling of channels is desi gned to be used in devices for the recording and development of holograms o n photothermoplastic materials. The device ensures the obtainment of nanose cond radiation pulses (similar to 30 ns, 0.01 J) of the second harmonic for exposure of photothermoplastic media and millisecond (similar to4 ms, 0.5 J) IR radiation pulses at the fundamental frequency for proximate developme nt of relief-phase holograms on photothermoplastic materials.
