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.
