A dye laser system used as a pulsed light source for picosecond photography of laser-produced plasma is described. The dye laser pulse has been synchronized with the iodine laser pulse by a combination of active-passive mode-locking. The arrival time of the dye laser pulse relative to the iodine laser pulse can be preselected with a jitter of 200 ps. Successful synchronization between the two pulse was obtained in 76% of all the shots taken.
