利用环型稳频倍频YAG激光器的倍频绿光(0.53μ)作为泵浦光,通过OPO腔中双KTP晶体的频率简并偏振非简并参量下转换过程,实现了腔内信号波、闲置波以及泵浦光的三模共振,并以期由此获得双模压缩光场。文中简要介绍了双模压缩态
By using the frequency-doubling green light (0.53μ) of circular frequency-stabilized frequency doubling YAG laser as the pump light, the intracavity signal wave is achieved through the frequency degenerate polarization non-degenerate parametric down conversion of the double KTP crystal in the OPO cavity, Idle wave, and triplet mode resonance of the pump light, and thus obtain a dual mode squeezed light field. The article briefly introduces the two-mode squeezed state
