摘要

压缩态光场是连续变量量子信息科学研究的重要资源。本文提出了一种利用级联的单共振倍频系统提高压缩度的方案,研究表明两次倍频分别产生的二次谐波与四次谐波场为压缩态光场,且四次谐波场的压缩度比二次谐波场提高了大约3 dB。我们还研究了两个谐波场的压缩度随泵浦场衰减率、泵浦功率的变化关系。该系统不仅可以增强压缩态光场的压缩度,而且能将压缩光拓展到更短的波长区域。此外,通过对波长1 014.8 nm的基频光进行四倍频获得与汞原子吸收线波长相对应的压缩光场,对量子存储、光谱测量和光频标具有实用价值。

Abstract

Squeezed light field is an important resource for the Continuous Variable quantum information science. In this paper, we propose a scheme of improving the squeezing level by a single resonance cascaded frequency doubling system. The results show that the second and fourth harmonic fields generated from the frequency doubling process are both squeezed states, and the squeezing of the fourth harmonic field is higher than the second harmonic field by about 3 dB. We also investigate the relation of the squeezing of the two harmonic fields relying on the decay rate of the pump field. This kind of system not only can obtain a higher squeezing level,but also can expand the squeezed band to a shorter wavelength. In addition, one can obtain a squeezed field of the mercury absorption line by fourth frequency doubling processes of a light field with wavelength 1 014.8 nm, and it may be practical valuable to quantum storage, spectral measurement, and optical frequency standard.
