Abstract

Dye-laser pulses of duration less than 300 fsec and tunable over a range of 400 Å have been generated by synchronous pumping with the ultrashort pulses from the fiber-optically compressed second harmonic of a Nd:YAG laser. Optical pulses as short as 210 fsec are reported in this ultrashort-pulse-pumping arrangement that does not require the use of saturable absorbers. With continuous temporal tuning of the duration of the compressed pump pulses, we have made the first reported investigation of the dynamics of synchronous mode locking as a function of pump-pulse width. We describe a method for the generation of tunable femtosecond dye-laser pulses that should be applicable to the large class of visible and near-infrared dyes that can be pumped by a frequency-doubled Nd:YAG laser.
