LASER CONTROL SYSTEMS

摘要

A laser control system comprising an energy source (10) adapted to feed a gain medium of a laser, wherein the energy source is arranged to supply continuous power at a level below laser threshold, further comprising means (13, 15) for boosting the level of the continuous power to a higher level for a predetermined period before the laser is fired and closed loop feedback circuit comprising means (17, 22) for monitoring the output laser energy of the laser and monitoring the magnitude of the power supplied by the power supply unit (11) in a sense to maintain the output from the laser substantially uniform.
