A scheme is proposed, in which the pulse train of squeezed light is generated via forward four-wave mixing through a nonlinear medium with third-order polarizability, coherently pumped by a train of pulses of modelocked laser. One of the quadrature noise compoments of the squeezed light is measured with a balanced homodyne detector using a pulse train as the local oscillation. The theoretical results show that the fairly high-intensity output of squeezed light can be achieved, and the noise-power spectrum of the light is almost completely squeezed and exhibits the form of a train of pulses, but the shape of squeezed spectrum is reversed with respect to that of the pulse train of the input light.
