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...http://www.google.es/patents/US5034951?utm_source=gb-gplus-sharePatente US5034951 - Femtosecond ultraviolet laser using ultra-thin beta barium borate
