Colored conical emission via spatiotemporal modulational instability was observe d in second harmonic generation of untrashort laser pulses. By injecting accurat ely synchronized white_light super_continuum seed pulses, frequencies with maxim al gain corresponding to the seed angle were amplified. The amplified pulse exhi bited 150 μJ pulse energy and 60 nm spectral width (full width at half maximum) centered around 500 nm. Wide tunable range of the output wavelength up to 290 n m was realized by adjusting the input angle of the seed pulses.
