Abstract: | A laser system comprising a synchronously pumped picosecond dye laser with combined cavity-distributed feedback and a two-stage
dye amplifier is described. The dependence of the laser pulse duration on the detuning of the cavity length, the pumping level
of the active medium, and the pulse number in the pulse train was investigated. It is shown that the combination of the two
types of feedback provides more than ten-fold shortening of the dye laser ultrashort pulse duration.
