ABSTRACT
Laser performances around 1.3 µm are investigated in 879 nm laser diode (LD) end pumped Nd3+ doped mixed crystals with NdGd0.69Y0.3TaO4 and NdGd0.68Y0.3NbO4 crystals for the first time to our best knowledge. The maximum average power in LD end pumped NdGd0.69Y0.3TaO4 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 NdGd0.68Y0.3NbO4 laser at 1337 nm is 190 mW at 50 Hz, corresponding to an optical-to-optical efficiency of 3.5% and a slope efficiency of 4.2%.
