摘要：

A spatially-broadband optical parametric amplifier is used for image amplification. In the phase-sensitive configuration, we observe a noise figure of -0.1+/- 0.3 dB for a gain of 2.4, which is 2 dB lower than the quantum limit for an ideal phase-insensitive amplifier. Image pre-amplification before loss is shown to improve the detected signal-to-noise ratio.
