Abstract
The output of a frequency-doubled cw mode-locked Nd:YAG laser has recently been fiber-optically compressed 80X to a duration of 410 fsec.1 This source of ultrashort 0.532-µm optical pulses has also recently been used to pump synchronously a rhodamine 6G dye laser resulting in dye laser pulses of <300-fsec duration and tunable over a 400-Å range.2 Dye laser pulses as short as 210 fsec have been generated by this ultrashort pulse-pumping technique and represent the shortest pulses obtained directly from a synchronously mode-locked dye laser (containing no saturable absorber).
