本文首次报道了用10 mm长5.0 μ m周期极化LiNbO（3）（PPLN）晶体实现的边发射二极管激光器腔内倍频（ICFD）。在1.0 A的注入电流下，产生了33 mW的490.5 nm的二次谐波蓝光的光输出功率，相当于1.8%的整体壁插效率。蓝光束的M（2）值沿快轴和慢轴沿着分别为1.7和2.4。
We demonstrate for the first time to our knowledge intra-cavity frequency doubling (ICFD) of an edge-emitter diode laser using a 10 mm-long 5.0 microm periodically poled LiNbO(3) (PPLN) crystal. An optical output power of 33 mW second harmonic blue light at 490.5 nm is generated at 1.0 A injection current, equivalent to an overall wall-plug efficiency of 1.8%. The measured M(2) values of blue beam are 1.7 and 2.4 along the fast and slow axis.
