AULA CHICA 

TÍTULO: "NON-DEGENERATE OPTICAL PARAMETRIC OSCILLATOR BEYOND ROTATING
WAVE APPROXIMATION"  

EXPOSITOR: SWAPAN MANDAL 

_DEPARTMENT OF PHYSICS, VISVA-BHARATI, SANTINIKETAN, INDIA_ 

RESUMEN: Under strong pump condition, the Hamiltonian and hence the
equation of motion of the field operators of a non-degenerate parametric
oscillator is formulated. The coupled operator differential equations
involving the signal and idler fields are solved analytically up to the
second order in dimensionless interaction time. We do not use the
rotating wave approximation (RWA) for getting these analytical
solutions. These solutions are used to investigate the squeezing, mixed
mode squeezing, amplitude squared squeezing and principal squeezing of
the input light prepared in composite coherent and in Fock states.
Interestingly, the squeezing, mixed mode squeezing etc  are unavailable
if the rotating wave approximated solutions are used. In spite of the
inexactness of the solutions, we are successful in getting various
nonclassical properties of the radiation field. We believe the approach
and hence the solution is fresh and will be of use for further
investigation on non-degenerate parametric oscillator.
