Abstract

chi((3))-nonlinear optical interactions in two melilite-type stimulated Raman scattering (SRS)-active non-centrosymmetric crystals, Ca(2)MgSi(2)O(7)and Ca2Ga2SiO7, formerly known as Nd3+-laser media, are presented. Under picosecond pumping at 1.064 and 0.532 mu m cascaded and cross-cascaded effects occur in these tetragonal silicates. Besides the SRS-promoting phonon modes with energy of omega(SRS1)approximate to 908 cm(-1)and omega(SRS2)approximate to 668 cm(-1)for Ca2MgSi2O7, and omega(SRS1)approximate to 720 cm(-1)and omega(SRS2)approximate to 550 cm(-1)for Ca2Ga2SiO7, respectively, combined phonon modes are observed. For Ca(2)MgSi(2)O(7)new data in a broad wavelength range of refractive indices and their dispersion are given as well. The observed chi((3))-nonlinear properties expand the functionality of the studied silicates and foreshadow their use in self-frequency Raman laser converters (self-SRS lasers).
