Abstract : We study the squeezing properties of the light generated by degenerate three and two-level lasers with non-degenerate sub-harmonic light and the cavity modes are coupled to a two-mode ordinary vacuum reservoir via a single port mirror We obtained c-number langevin equations associated with the normal ordering using the pertinent master equation. Making use of the solutions of the c-number langevin equations. The result shows that the two-mode light produced by the system is in squeezed. Moreover, it is found that 64% of squeezing below the coherent state at η = 0.04 for A = 100, κ = 0.8, Aa= 1, and ηa= 0.5. The effect of the two-level laser and parametric oscillator are to decrease and increase the properties of the quadrature squeezing.
Keywords : Lasers properties, sub-harmonic light, quadrature squeezing.
