摘    要:In this paper,we report an interesting phenomenon when precisely adjust the tuning crystal for double-resonance of a type-II configured parametric amplifier cavity,which is later verified as a cavity-enhanced effect in optics alignment.The theoretical result indicates that an angle accuracy error within 0.09 is necessary to achieve a high contrast ratio of 100:1 for a cavity with a finesse of about 205,which is crucial but high-demanding to get a high-quality narrowband entanglement source.Meanwhile,we figure out a method to release such a high requirement and get high visibility in a moderate-accuracy alignment.

Abstract:In this paper, we report an interesting phenomenon when precisely adjust the tuning crystal for double-resonance of a type-II configured parametric amplifier cavity, which is later verified as a cavity-enhanced effect in optics alignment. The theoretical result indicates that an angle accuracy error within 0.09o is necessary to achieve a high contrast ratio of 100:1 for a cavity with a finesse of about 205, which is crucial but high-demanding to get a high-quality narrowband entanglement source. Meanwhile, we figure out a method to release such a high requirement and get high visibility in a moderate-accuracy alignment.
Keywords:optics alignment  double-resonance  cavity-enhanced  narrowband entanglement
