We report the generation of subpicosecond light pulses in a cw mode-locked Oxazine 750 dye laser, utilizing combined synchronous pumping and saturable dye absorption effects. The latter were realized by either fractional cavity length configurations or composite gain-absorber media, which allowed stable operation in the tuning range 750–835 nm.
