Fixing of holograms recorded in a Fe-doped LiNbO3 crystal of 5 mm in thickness was achieved by heating with a CO2 laser. A series of 4 laser pulses at a power level of 7 watts and a total fixing time of 80 seconds was used. In this first demonstratio

Recording experiments on thin metallic films of lead and tantalum using a HeNe laser were first performed by Carlson, et al.1 in 1966. The laser beam focused to a microscopic spot onto the film raised its temperature and produced a permanent change w
