利用飞秒激光刻蚀技术在Nd：YAG晶体中制备了Y分支矩形包层波导。这种新颖的配置制造的深度为50 μm，支持TM和TE偏振的多模制导。在808nm光泵浦下，实现了1.06 μm波长的连续激光振荡。在分束角为0.5°时，器件的最大输出功率为0.2W，斜率效率为20%。
Rectangular Y-branch cladding waveguides have been fabricated in Nd:YAG crystal by femtosecond laser inscription. Such novel configurations are fabricated with depth of 50 μm, supporting multimode guidance in both TM and TE polarizations. Continuous wave laser oscillations at wavelength of 1.06 μm have been achieved under the optical pump at 808 nm. The maximum output power is 0.2 W with a slope efficiency of 20% in the device with splitting angle of 0.5°.
