Measurement of Raman gain of the S(8) transition of N(2).
The ratio of the rotational Raman gain coefficients g of N(2) [S(8), 0.91 amagat] and H(2) [S(1), 0.73 amagat] was determined at 295 K by measuring the 5% conversion threshold for each in the same focused configuration, using a circularly polarized 1054-nm laser. After correcting for dispersion, the optical Stark effect, transient effects, laser-wing Stokes seed injection, and mode-beat intensity modulation, we obtained g(N(2))/g(H(2)) = (8.0 +/- 1.2) x 10(-3), so that g(N(2)) = 4.0 +/- 0.8 cm/TW.
