Laser performances around 1.3 μm are investigated in 879 nm laser diode (LD) end pumped Nd doped mixed crystals with Nd:GdYTaO and Nd:GdYNbO crystals for the first time to our best knowledge. The maximum average power in LD end pumped Nd:GdYTaO 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:GdYNbO 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%.
据我们所知，首次对879纳米激光二极管（LD）端面泵浦掺钕混合晶体（Nd:GdYTaO和Nd:GdYNbO晶体）中1.3微米左右的激光性能进行了研究。LD端面泵浦Nd:GdYTaO 1328纳米激光器在50赫兹时的最大平均功率达到435毫瓦，光光效率为5.0%，斜率效率为6.9%。相比之下，LD端面泵浦Nd:GdYNbO激光器在1337纳米处50赫兹时的最高平均功率为190毫瓦，对应的光光效率为3.5%，斜率效率为4.2%。
