Abstract

New Yb:YVO₄ and Yb:Gd_xY_1-xVO₄ (x=0.6) laser crystals were grown by the Czochralski methods. The experimental spectroscopic properties of trivalent ytterbium ions in tetragonal vanadates have been performed. Polarized absorption and fluorescence spectra were investigated and stimulated emission cross sections were estimated for both crystals at room (RT) and liquid nitrogen (LN) temperatures. On the absorption and fluorescence data, excited states lifetimes the energy of electronic levels of ytterbium in crystalline hosts were calculated and the lasing parameters of broadband transitions of doped ions were studied. The investigation shows these crystals are perspective for femtosecond pulses generation in NIR region near 1000 nm under laser diode pumping.
