Generation of infrared radiation by stimulated Raman scattering in para-hydrogen crystal at 5 K

Abstract

We report the preliminary results of our experiments with stimulated Raman scattering in para-hydrogen crystal aimed at developing a continuously tunable laboratory laser source of mid-infrared radiation. With laser pulses at 532 nm, a conversion efficiency for the first Stokes beam of as much as 20% in the forward direction was observed through a single-pass, 5-cm-long crystal. Generation of mid-infrared pulses at $4.5 \mathit{\mu }\mathrm{m}$ was achieved by use of the output of a near-infrared pulsed laser $(1.6 \mathit{\mu }\mathrm{m}$, 3 ns), and an absorption spectrum of gaseous CD₄ molecules was successfully recorded. These results suggest use of the solid para-hydrogen Raman shifter as a promising light source for mid-infrared spectroscopy.
