Abstract
We report on a 928â¯nm laser based on quasi-three-level transition of 4F3/2â¯ââ¯4I9/2 in a Nd:Gd0.69Y0.3TaO4 mixed single crystal. With LD pumping at 808â¯nm, an output energy of 29.8â¯mJ at 928â¯nm is achieved with an optical-to-optical efficiency of 16.5% and a slope efficiency of 21.2%. In comparison, using 879â¯nm LD pumping, the maximum output energy at 928â¯nm reaches 48.5â¯mJ with an optical-to-optical efficiency of 33.4% and a slope efficiency of 38.0%.
