Abstract
The thermal lensing effect generated in an end-pumped lightly doped Nd:GdVO 4 crystal was found to be considerably weaker than that in Nd:YVO4 having t he same Nd3+ concentration. Consequently, the laser performance of Nd:GdVO4 at high pump powers over 20 W was found to be superior to that of Nd:YVO4. TEM00 mode cw radiation of 14.3 W at 1.06 mu m was achieved with an optica l conversion efficiency of 55%, and average slope efficiency of 62%.
