Generating and Detecting Short-Duration Pulses of Squeezed Light

Mode-locked lasers provide a train of high intensity light pulses that can be used to pump nonlinear media in order to produce squeezed light. The squeezed light produced would consist of a train of short duration pulses. It is shown here that a homodyne detector using a pulsed local oscillator can be used to observe the squeezing even when the response time of the photodetector is much longer than the local oscillator or squeezed light pulse width.
