Abstract

We demonstrate pulsed full-color digital holography with a hydrogen Raman shifter as a single source of highly directional multiwavelength light. For the primary (blue, green, red) color channels we utilize the first three Stokes beam outputs (415.9, 502.9, and 635.9 nm) of the shifter (gas pressure, 1.38 MPa) that is pumped by the 355-nm output of a pulsed Nd:YAG laser (5.4-ns pulse width, 10-Hz repetition rate). We have developed a simple beam-conditioning system to improve the transverse intensity distribution for the individual Stokes beams and to equalize their relative intensities. Full-color holographic imaging is demonstrated with transmitting and reflecting colored objects. Also, the optical noise characteristics of the reconstructed images are investigated.
