We generate an enhanced blue-shifted continuum in bulk Kerr media in ultrashort laser pulse filamentaiton at 1055 nm. At threshold, a spectrally isolated blue peak appears, while at higher energies the continuum expands from the blue peak and spans more than an octave in the spectrum. The central wavelength of the peak can be tuned in a 150 nm range. The effect is explained in terms of X-waves generation.
