Abstract : The patent concerns a dye laser for holographic applications. Q switched ruby laser is used to pump the dye laser using Rhodamine-6G as the dye. The dye laser is pumped with a Q-switched ruby laser having its 6,943 A output beam frequency-doubled with a KDP crystal. The light beam of 3,472 A so obtained is applied to pump the dye laser in a longitudinal arrangement using a dispersing prism. The resultant tunable dye laser output is then applied for recording holograms. Multi-stage systems and cascade spectrum narrowing of the dye laser output are used to increase the overall efficiency for holographic applications.
