Abstract
Colored conical emission via spatiotemporal modulational instability was observed in second harmonic generation of ultrashort laser pulses. By injecting accurately synchronized white-light super-continuum seed pulses, frequencies with maximal gain corresponding to the seed angle were amplified. The amplified pulse exhibited 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 nm was realized by adjusting the input angle of the seed pulses.
