“…Meanwhile we notice that these calculated values are larger than those recently obtained by Hodgson et al 18 This is due to the fact that only temperature-dependent thermal focal lensing was considered in Hodgson's calculations; while the end effect was neglected. The thermal lensing coefficient for a laser material is a constant and can serve as a figure of merit for the thermal properties.…”

The thermal effects of diode-end-pumped Nd:YVO 4 and Nd:YAG lasers are analyzed by a 2-D analytical model and a 3-D numerical model, respectively. The characteristics of the Nd:YVO 4 and Nd:YAG rods are comparatively discussed, including temperature distributions and thermal lensing effects. The model quantitatively separates the end effect from the index parts. Under the same pump configuration, we find that the temperature increase in the Nd:YVO 4 laser was 2 times larger than those in the Nd:YAG laser, while the thermal lensing coefficient of Nd:YAG was 27% higher than that of Nd:YVO 4 . We also conclude that a good roundness of the Nd:YVO 4 laser beam profile is expected because nearly symmetric thermal lensing in the a and c axes is predicted from our modeling and measurement. Correspondingly, we perform experiments that are in good agreement with theoretical modeling for the thermal lensing of diode-pumped Nd:YVO 4 and Nd:YAG lasers.

We comparatively studied laser performance in the mixed vanadate crystals Nd:Y x Gd 1-x VO 4 with direct and indirect pumping. The maximum CW output power at 1064 nm was measured to be 6.6 W with 12 W direct 880 nm laser diode pumping, and 4.4 W with 8.8 W indirect 808 nm pumping. The optical conversion efficiency depended on the mixture ratio (x), pumping wavelength (direct or indirect), and pumping power. The hightest optical efficiency of 59% and slope efficiency of 74% were achived.
