Abstract
Employing the master equation for a three-level laser driven by coherent light and
coupled to a squeezed vacuum reservoir, we obtain stochastic differential equations
associated with the normal ordering. Using the solutions of the stochastic differential
equations, we calculate the quadrature variance, the squeezing spectrum, the mean
photon number, and the variance of the photon number. It turns out that the degree
of squeezing increases with the linear gain coefficient or the squeeze parameter. It is
also found that the driving coherent light decreases the mean photon number
