Since its development in 1980, the colliding pulse passively mode locked (CPM) dye laser has proved to be an excellent source of ultrashort pulses. However, most of the systems use the active-passive dye combination of Rhodamine 6G/DODCI operating around 620 nm. In recent years, several active/passive dye combinations have been studied yielding subpicosecond pulses from 487 nm to 810 nm [1,2]. We report here the generation of pulses as short as 36 fs around 775 nm from a CPM dye laser with an intracavity GVD compensation. These pulses are the shortest, to our knowledge, never produced in a passively mode locked dye laser in the near infrared.
