    "abstract": "We present a Gaussian state description of squeezed light generated in an\noptical parametric oscillator. Using the Gaussian state description we describe\nthe dynamics of the system conditioned on homodyne detection on the output\nfield. Our theory shows that the output field is squeezed only if observed for\nlong enough times or by a detector with finite bandwidth. As an application of\nthe present approach we consider the use of finite bandwidth squeezed light\ntogether with a sample of spin-polarized atoms to estimate a magnetic field.",
