ABSTRACT:
A method and apparatus for generating a light pulse having a duration as short as about 3 picoseconds is disclosed. A 5 mJ 25 picosecond second harmonic light pulse from a Nd:YAG laser system is focused into a 5 cm cell filled with D.sub.2 O so as to generate a continuum light pulse spanning about 150 nanometers with an average energy of at least 20 nd
m across the spectrum. The continuum light pulse is fed through a 10 nanometer narrowband filter centered at 580 nanometers, producing an output pulse having a duration of about 3 picoseconds. The pulse so produced has a number of uses including as a seed pulse for dye laser oscillators and solid state amplifiers or as a pump source for pumping ultrashort dye lasers.
