Abstract
We suggest a variant of the proposed experiment for the generation of a new kind of mesoscopic superposition quantum states, using two coupled paramet ric down-converter nonlinear crystals [F. De Martini, Phys. Rev. Lett. 81 ( 1998) 2842]. We study the parametric oscillator case and find that an entan gled Schrodinger-cat type state of two cavities, whose mirrors are placed a long the output beams of the nonlinear crystals, can be realized under suit able conditions.
