Abstract
A laser pulse generator utilizes intracavity doubling in an ultrathin beta barium metaborate crystal to produce femtosecond pulses in the ultrashort ultraviolet wavelength range. The generator includes a colliding-pulse passively mode-locked ring dye laser which propagates a pulsed beam of primary laser light in a cavity. The primary light beam has a repetition rate of 10.sup.8 Hz and a pulse width in the femtosecond range. The crystal is located in the cavity so that the primary beam strikes one crystal surface at Brewsters angle and propagates through the crystal at its phase-matching angle. The primary beam and its second harmonic are emitted from the opposite surface, the harmonic wave having the same repetition rate and substantially the same width as the primary beam, but one-half its wavelength.
