摘　　要：阐述了一具体实验现象 :LD泵浦掺钕矾酸钇固体激光器输出激光再驱动 ( KTP)倍频晶体产生倍频绿激光输出的系统 ,存在严重噪声 ,但可通过改变入射角 ,用对应的特定频率调制 。This paper illustrates a detailed experimental phenomenon.The system has serious noise,in which the solid laser of laser diode pump coupled with Nd:YVO 4 outputs laser beam to drive KTP and produce green laser beam.However,the noise can be decreased to the extreme minimum value by changing the angle of incidence and modulating in the corresponding special frequency.
