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