Description
  • The comparative study of the multi-wave stimulated Raman scattering (SRS) oscillation in PbMoO4 and PbMo0:5W0:5O4 crystals under 18-ps laser pumping at the wavelength of 1064 nm is carried out. It is shown that because of four-wave mixing of the Raman radiation components in the crystals with a short length (1 cm) the oscillation thresholds of the 2nd (at the wavelength of 1306 nm) and the 3rd (at the wavelength of 1473 nm) Stokes radiation components are significantly reduced relative to the values defined by the cascade mechanism of stimulated Raman scattering. At the same time in the PbMo0:5W0:5O4 composite crystal the multi-Stokes SRS oscillations were observed containing different combinations of the Raman frequency shifts corresponding to a structure of the plumbic molybdate and tungstate. At the 1st Stokes radiation component, splitting to the wavelengths of 1173 and 1178 nm, the Raman shifts of 869 cm-1 (plumbic molybdate structure) and 904 cm-1 (plumbic tungstate structure) were observed. At the 2nd Stokes radiation component, splitting to three wavelengths of 1306, 1312, and 1318 nm the frequency shifts of 2869 cm-1, (869 + 904) cm-1, and 2904 cm-1, respectively, from the pumping wave were observed.
