  We propose a method for tailoring the frequency spectrum of bright squeezed
vacuum by generating it in a nonlinear interferometer, consisting of two
down-converting nonlinear crystals separated by a dispersive medium. Due to a
faster dispersive spreading of higher-order Schmidt modes, the spectral width
of the radiation at the output is reduced as the length of the dispersive
medium is increased. Preliminary results show 30\% spectral narrowing.
