Abstract
An interaction scheme involving nonlinear chi((2)) media is suggested for the generation of phase-coherent states (PCSs). The setup is based on parametric amplification of the vacuum followed by up-conversion o f the resulting twin beam. The involved nonlinear interactions are stu died by the exact numerical diagonalization. An experimentally achieva ble working regime to approximate PCSs with a high conversion rate is given and the validity of the parametric approximation is discussed.
