Abstract

Laser performances around 1.3 μm are investigated in 879 nm laser diode (LD) end pumped Nd3+ doped mixed crystals with Nd:GYTO and Nd:GYNO for the first time to our best knowledge. The maximum average power in LD end pumped Nd:GYTO 1328 nm laser reaches 435 mW at 50 Hz with an optical-to-optical efficiency of 5.0% and a slope efficiency of 6.9%. In comparison, the highest average power of LD end pumped Nd:GYNO laser at 1347 nm is 190 mW at 50 Hz, corresponding to an optical-to-optical efficiency of 3.5% and a slope efficiency of 4.2%.
