We present a quantum-mechanical analysis of an above-threshold laser amplifier made phase sensitive by an injected field. The gain and noise are calculated in a high-Q cavity with four-level atoms as the lasing medium. We find that for coherent-state inputs this amplifier can preserve the signal-to-noise ratio thus achieving the theoretical best noise performance.
