Abstract
Variable attenuation of a light beam is achieved by mounting a rotatable multilayer dielectric attenuator in the beam. A first portion of the beam is transmitted through the attenuator and a second portion is reflected. Rotation of the attenuator about an axis transverse to the beam varies the ratio between these portions. The main application of this attenutator is to control an output characteristic, e.g. output power, of a laser, and may include a feedback loop to maintain this characteristic constant.
