Abstract

Recently Milburn and Walls¹ published an analysis of a parametric amplifier with cavity losses included. With the cavity configuration they chose to analyze that the maximum amount of squeezing that could be achieved was a factor of 2. It is demonstrated here that suitably constructed cavity-degenerate-parametric amplifiers and cavity-four-wave mixers are capable of producing a large amount of squeezing near the threshold of oscillation. High finesse reduces the amount of gain from a parametric medium or reflectivity from a four-wave-mixing medium needed in order to achieve an appreciable amount of squeezing.
