Subpicosecond pulses from a tunable cw mode-locked dye laser

Abstract

Tunable subpicosecond pulses (pulse width =0.8 psec) have been obtained from a cw mode-locked Rhodamine B dye laser. Mode locking is achieved by synchronous pumping of the Rh-B dye with a cw train of pulses which are obtained from a synchronously mode-locked Rhodamine 6G dye laser.
