Abstract

Spectroscopic properties of Nd:GdVO<sub>4</sub> were investigated, and it was found that its absorption and emission cross sections were smaller than those of Nd:YVO<sub>4</sub>. And by using Nd:GdVO<sub>4</sub> the near quantum-limit laser oscillation was demonstrated. The highest optical-to-optical efficiency of 79.0% has been achieved in 1-?m cw laser oscillation by Nd:GdVO<sub>4</sub>, where slope efficiency was 80.3% with respect to the pump input power.
