The ability of crystal violet to mode-lock the rhodamine 6G laser is reported. The relaxation time of crystal violet is solvent dependent. The manner in which the mode-locking is affected by varying this relaxation time is described. A 2 mm path of a .00003 M solution of crystal violet in glycerol having a relaxation time of 100 ps, gave the best quality mode-locking for the 48 cm long x 8 mm diameter dye laser used. (Author).
