摘要

Solid para-H_(2) is a promising gain medium for stimulated Raman scattering, due to its high number density and narrow Raman linewidth. In preparation for the design of a cw solid hydrogen Raman laser, we have made the first measurements, to our knowledge, of the index of refraction of a solid para-H_(2) crystal, in the wavelength range of 430-1100 nm. For a crystal stabilized at 4.4K, this refractive index is measured to be n_(p-H_(2)) velence 1.130 +- 0.001 at 514 nm. A slight, but significant, dependence on the final crystal-growth temperature is observed, with higher n_(p-H_(2)) at higher crystal-growth temperatures. Once a crystal is grown, it can be heated up to 10K with no change in n_(p-H_(2)). The refractive index varies only slightly over the observed wavelength range, and no significant birefringence was observed.
