2ND-ORDER AND AMPLITUDE-SQUARED SQUEEZING OF THE 2 2-LEVEL ATOMS WITHSUPERPOSITION STATE PREPARATION

An analysis of the second-order and amplitude-squared (AS) squeezing i s Presented for the two atoms prepared in a two-atom squeezed state us ing coherent and squeezed field inputs. The system produce strong sque ezing and superposition angle (theta) is more effective for small valu es of average photon number ((n) over bar) as compared to that of larg e one. The degree of squeezing of both types increases as theta increa ses for coherent field input with small (n) over bar. Some values of t heta for the initial field in a squeezed-vacuum state with any value o f input squeezing can make one of the quadrature of the both types of squeezing permanently squeezed for T greater than or equal to 0. For t he initial field in a more general squeezed state, the second-order an d AS squeezing behave randomly for different values of theta.
