Abstract
An attenuation optical system is in a beam path of a light beam traveling through a regenerative ring resonator. The attenuation optical system includes an actuator configured to receive an electromagnetic signal; and a plate mounted to the actuator to be moveable between a plurality of positions, with each position placing an attenuation region in the beam path such that the beam profile is covered by the attenuation region and each attenuation region representing an attenuation factor applied to the light beam as determined by a geometry of the attenuation region. At least one attenuation region includes a plurality of evenly-spaced elongated openings between solid energy-reflecting surfaces and at least one attenuation region includes an open area that is larger than the beam profile of the light beam.
