Abstract

Optical spectra and luminescence decay curves were measured for erbium-doped Y V O 4 and Gd V O 4 single crystals as a function of temperature in the 300 K 670 K temperature region. In spite of structural similarity the two systems studied display significantly different transition intensities and nonradiative relaxation rates. It was found in particular that the intensity of parasitic upconverted emission excited at 978 nm depends weakly on temperature for Y V O 4 : Er 3 + , whereas it decreases monotonously with increasing temperature for Gd V O 4 : Er 3 + and becomes negligibly small at 670 K . It was concluded that Gd V O 4 : Er 3 + may be a promising laser active material operating at high thermal loading conditions encountered in high-power diode-pumped IR lasers.
