We report efficient, diode-pumped, self-frequency doubling (SFD) in the newly developed laser crystal Nd3+:Na3La9O3(BO3)8 (Nd:NLBO). More than 730 mW of fundamental output power at 1072 nm was achieved with a slope efficiency of 16.2%. With incident pump power of 8 W, 29 mW of green cw laser emission at 536 nm was observed with proper phase matching. This initial performance and the good optical properties of the crystalline host are encouraging for the development of a high power diode-pumped SFD visible light laser source.
我们报告了在新开发的激光晶体 Nd3+:Na3La9O3(BO3)8 (Nd:NLBO) 中实现高效、二极管泵浦、自倍频 (SFD)。在 1072nm 处获得了超过 730mW 的基频输出功率，斜率效率为 16.2%。在 8W 的入射泵浦功率下，观察到 536nm 处 29mW 的绿光连续波激光发射，相位匹配得当。这种初始性能和晶体基质的良好光学性质为开发高功率二极管泵浦 SFD 可见光激光源提供了希望。
