Abstract
•Experimental and numerical data on Stokes generation are collated to retrieve Raman gain coefficient g0.•Feasibility of the approach is tested on a sample of barium nitrate.•g0 values are determined in two orientations of potassium-gadolinium tungstate sample at 532 nm wavelength.
Stokes generation has been considered under the Fourier-limited nanosecond pulse excitation to find Raman gain coefficients in potassium-gadolinium tungstate. Data of numerical simulation under spontaneous Stokes initiation, light diffraction, and optical feedback have been compared with experimental results to reveal coefficient values of 14 ± 3 and 11 ± 3 cm/GW for the p[mm]p and p[gg]p sample orientations, respectively, at 532 nm wavelength.
