    "abstract": "Applying stochastic differential equations, we study the squeezing and\nstatistical properties of the cavity and output modes of a degenerate\nthree-level laser whose cavity contains a parametric amplifier and coupled to a\nsqueezed vacuum reservoir. We consider the case in which the top and bottom\nlevels of the three-level cascade atoms injected into the cavity are coupled by\nthe pump mode emerging from the parametric amplifier. It turns out that the\npresence of the squeezed vacuum reservoir and the parametric amplifier\ncontribute considerably to the mean photon number and the degree of squeezing\nof the cavity and output modes. It appears that almost perfect squeezing can be\nachieved at steady state and at threshold for a suitable choice of parameters.",
