| Abstract: | In single-pass configuration, a picosecond pulse laser was used to investigate the stimulated Raman scattering in different BaWO4 crystals. Using the thresholds for the first Stokes line along the a- and c-axis, the Raman gain coefficients of the BaWO4 crystals were calculated along their respective direction. The higher Stokes (fourth) and anti-Stokes (third) lines were observed. Compared with other well-known Raman crystals, such as KGd(WO4)2 and Ba(NO3)2, BaWO4 has favorable properties for scattering the pump radiation with picosecond pulse duration. The Raman gain coefficients of BaWO4 are different, but do not vary for different transmission directions, which means that this Raman material can be selected more freely. |
