Abstract

A double-slit object is illuminated by the signal beam and imaged via a × 1 telescope into the optical parametric amplifier (OPA). The signal is polarized with respect to the optic axis of the 1.6-mm KTP crystal. The pump is weakly focused into the crystal. The phase of the pump relative to the signal is stabilized to maximize the gain. The uniformity of the parametric gain of the OPA over the photodetector's bandwidth enables estimation of the signal-to-noise ratio (SNR) by relating the near-dc intensity gain to the noise-power gain at 27 MHz.
