摘要：

We propose and demonstrate a system that produces squeezed vacuum using a pair of optical parametric amplifiers (OPAs). This scheme allows the production of phase sidebands on the squeezed vacuum which facilitate phase locking in downstream applications. We observe strong, stably locked, continuous wave vacuum squeezing at frequencies as low as 220 kHz. We propose an alternative resonator configuration to overcome low frequency squeezing degradation caused by the OPAs.
