1. A method of controlling the timing of output pulses from a laser for use in a device which requires scanning of the laser output, wherein each output pulse is generated in response to a pump pulse comprising the steps of:

  • monitoring the time delay between the initiation of the pump pulses and the subsequent generation of the associated output pulses;

    predicting the time delay between the initiation of next pump pulse and the associated output pulse based on the monitored time delays and;

    initiating the next pump pulse at a time selected to insure the output pulse is generated at a time to permit proper positioning of the laser output during the scan of the beam.
