Remote control of ruby laser pulse length could be achieved over 2 orders of magnitude. The technique for generating such a variability of pulse lengths with the same laser makes use of well-known cavity dumping and mechanical or simple electronic modifications. Short pulses could be lengthened by increasing the parallel capacity of a laser-triggered spark gap.
