Abstract

Method and system provide a variable delay between the external trigger pulse for a laser system and the light pulse such that the total delay is controlled. The method and system utilize a digital time measuring circuit which measure a time interval which corresponds to a time between the generation of the trigger pulse and generation or a laser light pulse. Based on the measurement by the digital time measuring circuit a processor controls a delay circuit which thereby controls the time between the trigger pulse and the generation of the laser light pulse.
