在室温下，通过对二极管端面泵浦的Nd:Y₃Al₅O₁₂激光器进行倍频，从一个8.5毫米长的无涂层周期性极化MgO:LiNbO₃脊型波导中产生了473纳米、189毫瓦的连续波功率，转换效率为49%；相应的内部蓝光功率和转换效率分别为222毫瓦和58%。从一个12毫米长、蓝光输出功率为99毫瓦的波导中获得了63%的最高转换效率（相对于内部蓝光功率为74%）。当耦合到波导中的基频功率超过200毫瓦时，观察到输出蓝光功率饱和。（C）2003美国物理学会。
Continuous-wave power of 189 mW at 473 nm with 49% conversion efficiency is generated from a 8.5 mm long uncoated periodically polled MgO:LiNbO3 ridge-type waveguide by frequency doubling of a diode end-pumped Nd:Y3Al5O12 laser at room temperature; the corresponding internal blue power and conversion efficiency were 222 mW and 58%, respectively. The highest conversion efficiency of 63% (74% with respect to the blue internal power) was obtained from a 12 mm long waveguide with 99 mW blue output power. Saturation of output blue power was observed for coupled fundamental power into the waveguides in excess of 200 mW. (C) 2003 American Institute of Physics.
