We report the first ever femtosecond supercontinuum generation in a KDP crystal using ~100 fs pulses at 790 nm irradiation. Due to the quadratic nonlinearities of the KDP crystal an enhanced bandwidth of 385 -960 nm is generated. The spatial and temporal coherence of the generated white light is demonstrated using Young's double slit interference configuration and a Michelson interferometer.
