| Abstract: | We propose a novel scheme for the joint generation of two squeezed beams at arbitrary frequencies ω 1 and ω 2. The scheme consists of two successive steps, both involving nonlinear interactions in χ(2) crystals. The dynamics of the setup is analyzed both quantum mechanically and classically within the parametric approximation. An experimental implementation involving the fundamental and the harmonics of a Nd:YAG laser pulse, and β-BaB 2 O 4 nonlinear crystals is suggested.
