Spectroscopic and laser properties of Nd : Gd0.8La0.2VO4 crystal

The polarised absorption and fluorescence spectra of Nd: Gd0.8La0.2VO4 crys tal are measured and compared to those of Nd: GdVO4CW laser properties of d iode-pumped Nd : Gd0.8La0.2VO4 crystal operating at fundamental wavelengths of 1.06 and 1.34 mum as well as when intracavity frequency-doubled to 532 and 670 nm, have been studied. The maximum output powers at 1.06 im, 1.34 m um, 532 nm and 670 nm are 1.18 W, 671 mW, 206 mW and 42 mW respectively, at a diode-launched pump power of 2.9 W. The threshold pump powers are 80, 26 7, 7 and 15 mW respectively. (C) 2001 Published by Elsevier Science Ltd.
