Abstract:
In this thesis, we study the squeezing and statistical properties of light
produced by degenerate squeezed three level laser and one mode
subharmonic generator. We first obtain, the master equation, with the aid of
the master equation, we determine c-number Langevin equations for a
degenerate squeezed three level laser and one-mode subharmonic generator.
With the help of solutions of c-number Langevin equations, we also obtain the
antinormally ordered characteristic function defined in the Heisenberg
picture. The resulting characteristic function is used to determine the
Q-function of the light beams produced by degenerate squeezed three level
laser and a one-mode sub-harmonic generator. Finally we superposed the two
Q functions. Employing the resulting Q-function, we calculated the photon
statistis and quadrature fluctuation.And we have seen that squeezing is
enhanced for the superposed light beams.
