我们报告的连续波压缩真空共振Rb D1线（795 nm）使用周期性极化KTiOPO 4（PPKTP）晶体的产生。利用基于PPKTP晶体的倍频器和光参量振荡器，我们观测到了-2.75+/-0.14dB的压缩水平和+7.00+/-0.13dB的反压缩水平。该系统可用于演示压缩真空的存储和恢复，这对于原子自旋的超精密测量以及量子信息处理具有重要意义。
We report the generation of a continuous-wave squeezed vacuum resonant on the Rb D1 line (795 nm) using periodically poled KTiOPO4 (PPKTP) crystals. With a frequency doubler and an optical parametric oscillator based on PPKTP crystals, we observed a squeezing level of -2.75+/-0.14 dB and an antisqueezing level of +7.00+/-0.13 dB. This system could be utilized for demonstrating storage and retrieval of the squeezed vacuum, which is important for the ultraprecise measurement of atomic spins as well as quantum information processing.
