Picosecond infrared-continuum generation by three-photon parametric amplification in LiNbO3.
Picosecond infrared continua are produced by propagating an intense ultrashort 1.064-microm pulse through a LiNbO(3) crystal set near the degenerate point. Under our experimental conditions, gain broadening is identified as the principal mechanism leading to the superbroad spectral output.
