We have studied passive mode locking of the Ar/sup +/ laser using the saturable absorber rhodamine 6G in four different regimes as follows: when the Ar/sup +/ laser operates in the colliding pulse mode locking configuration (1) with and (2) without double mode locking incorporated and also when the Ar/sup +/ laser operates in the conventional configuration (3) with and (4) without double mode locking incorporated. A detailed investigation of the Ar/sup +/ and dye laser pulses from the double mode-locked Ar/sup +/--dye laser system is made using correlation measurements. A direct display of a 67-ps Ar/sup +/ pulse shape is measured. Parametric studies provide insight into the fundamental mechanisms involved in the production of the pulses, and also show that the colliding pulse regime, where two Ar/sup +/ pulses interact coherently in the saturable absorber, is favorable as far as stability and minimum pulse durations are concerned for this system.
