In this paper we present a squeezing operator for a pulsed squeezed light and give the concise expressions and the features of the intensity and noise as a function of time and frequency for the pulsed squeezing field. The generation for pulsed squeezed state light (PSSL) has been studied. In this paper we present a ket for PSSL and give the concise expressions of the intensity and the noise as functions of time and frequency and discuss their frequency features. We also propose a scheme in which the pulse train and the frequency spectrum of the noise can be simultaneously determined.

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.
