ABSTRACT:
Subpicosecond pulses less than 70 femtoseconds in duration are obtained with a synchronously pumped dye laser using a mixture of laser dye and a fast recovery saturable absorber which passes in a jet between folding mirrors in a laser cavity. The ratio of absorber to dye in the mixture is selected to compensate for dispersion effects in the laser medium which tend to limit the spectrum of the laser pulses and increase their duration.
