The picosecond laser pulse train emerging from a Nd30: glass laser mode-locked and Q switched by a saturable dye does not consist of only pulses separated by the round trip time of the laser cavity but contains extraneous satellite pulses, whose temporal positions depend on the relative position of the dye cell in the laser cavity. The ultrafast light gate technique is used to systematically investigate the temporal development of the pulse train. It is concluded that, in order to eliminate the satellite pulses, the dye should be placed in contact with the rear mirror or in a position such that no satellite pulse appears in the temporal interval of interest.
