Parametrically amplified ultrashort pulses from a shaped photonic crystal fiber supercontinuum

By seeding a noncollinear optical parametric amplifier with a photonic crystal fiber supercontinuum, temporally well-defined amplified output pulses have been generated with durations down to 13 fs. The phase of the supercontinuum seed has been characterized by the ZAP-SPIDER technique and can be tailored with a femtosecond pulse shaper. Thus, a very flexible source for arbitrarily shaped, amplified ultrashort laser pulses has been realized. (c) 2008 Optical Society of America.
