Abstract
Apparatus for optically controlling the output energy of a pulsed laser source comprising a laser producing a plurality of laser pulses in a laser beam. An optical attenuator is disposed in the laser beam to attenuate the energy in the laser beam to provide an attenuated laser beam, and a pick-off is provided for sensing the energy in the attenuated laser beam. A controller is coupled to the pick-off for controlling the optical attenuator to vary the energy in the attenuated laser beam to thereby vary the output fluence from the apparatus.
