| 摘 要： | 对腔内倍频LD泵浦的Nd:YAG激光器的输出稳定性进行了分析,以二型匹配为例,尽管存在任意多个纵模,当腔内放置1/4波片,论证了当1/4波片的快轴与倍频晶体的E轴夹角为45°时,便可获得稳定的蓝激光输出。并用模简并和光子对易的观点分析了上述方法的物理过程。

| Abstract: | The stability of the output light from a diode-pumped intracavity frequency-doubled Nd∶ YAG laser was analyzed. Type Ⅱ phase-matched an intracavity nonlinear crystal was used for frequency doubling. When the angle between fast axis of QWP, which was inserted in intracavity,and E axis of doubling crystal is 45°, the light output was stabilized although multilongitudinal-modes existed. The opinions of mode degeneracy and photon commutation are presented to explain the above method. |
