Abstract
We present a model for a two-photon phase-sensitive linear amplifier i n which the phase sensitivity is introduced by injecting three-level a toms initially prepared in a coherent superposition of upper and lower levels. We have studied the quantum-statistical properties of noise a nd show that, under certain conditions, the additive noise is in a squ eezed vacuum state whose squeezing parameter depends on the atomic var iables.
