Abstract

Synchronized femtosecond pulses of different wavelengths are desirable for many applications in ultrafast spectroscopy of semiconductors and molecules. Generation of synchronized pulse trains at high repetition rates (~ 80 MHz) was demonstrated in two-color Ti:sapphire lasers [1-3]. Unfortunatly, the tunability of these previously reported systems was strongly restricted, while the pulse durations were limited to above 50 fs. These limitations turned out to be a serious hindrance for widespread applications in experiment.
