title: Continuous-wave and passively Q-switched laser performance of LD-end-pumped 1062 nm Nd:GAGG laser.
abstract: Continuous-wave (CW) and passively Q-switched operations of LD-end-pumped Nd:Gd(3)Al(x)Ga(5-x)O(12) (Nd:GAGG) laser at 1062 nm were reported. The highest CW output power of 5.7 W was obtained, corresponding to an optical conversion efficiency and slope efficiency of 51.0% and 54.5%, respectively. The CW output efficiency of Nd:GAGG laser is comparable and even better than that of Nd:GGG. The passively Q-switched output was realized for the first time to our knowledge. In addition, a maximum output power of 1.12 W, a maximum pulse repetition rate of 39 kHz and a minimum pulse width of 6 ns were obtained by using Cr(4+):YAG as the saturable absorber.
