title: Passively Q-switched performance of a Nd:Gd3Ga5O12 eye-safe laser at 1423.4  nm with Co2+:LaMgAl11O19 as saturable absorber.
abstract: The performance of a LD-pumped passively Q-switched Nd:GGG eye-safe laser at 1423.4 nm with a Co(2+):LaMgAl(11)O(19) (Co:LMA) saturable absorber is demonstrated. A maximum average output power of 627 mW with an optical-to-optical efficiency of 3.35% and a slope efficiency of 5.1% was obtained under a pump power of 18.7 W. A minimum pulsewidth of 102 ns and a pulse repetition rate of 35 kHz were obtained with the T=1.0% output coupler.
