Squeezing and quantum non-demolition measurement with an optical parametric amplifier

Quantum effects in a degenerate parametric amplifier resonant for the subharmonic wave are studied. Good squeezing in the harmonic wave can be obtained using an injected subharmonic wave with appropriate amplitude and phase. Quantum nondemolition measurements of the phase or amplitude of the harmonic wave can be achieved by measuring the phase or amplitude of the deamplified injected subharmonic meter wave. The amplitude of the harmonic wave must be close to the threshold amplitude. Good correlations require a large mirror transmission relative to the internal dissipative meter losses.
