Abstract

We report the application of low-power cw laser sources in obtaining high-resolution stimulated Raman spectra (SRS) of the Q01 (1) transition in molecular hydrogen. Fully resolved spectra of both the real and the imaginary parts of the Raman susceptibility, obtained with a resolution of <25 MHz, show a motionally narrowed minimum linewidth of 250 ± 5 MHz. The cw SRS techniques reported herein should find a variety of applications in high-resolution Raman studies.
