DETERMINATION OF THE STEADY-STATE RAMAN GAIN COEFFICIENTS OF POTASSIUM-GADOLINIUM TUNGSTATE AT A WAVELENGTH OF 532 nm
Abstract
A method for determination of the steady-state Raman gain coefficients in crystals has been proposed. The method is based on comparing the numerical simulation data and the experimental Raman generation results. The proposed approach has been tested for barium nitrate in the field of spectrally limited nanosecond laser pulses. Its application for potassiumgadolinium tungstate has revealed the values of the Raman gain coefficients to be 14 ± 3 and 11 ± 3 cm/GW at a wavelength of 532 nm for the E║Nm and E║Ng sample orientations, respectively.
