Tetragonal vanadates YVO4 and GdVO4-new efficient X(3)-active crystals for Raman laser converters

High-order Stokes and anti-Stokes picosecond generation in tetragonal YVO 4 and GdVO 4 host crystals for lasing trivalent lanthanides (Ln 3+ ) has been observed for the first time. All measured stimulated Raman scattering (SRS) wavelengths in the visible and near infrared (NIR) are identified and attributed to the SRS-active vibration modes of these vanadates.
