Variable attenuator for Gaussian laser beams.
A method of attenuating laser beams is described, which is continuously variable, gives an output beam of constant Gaussian shape, and is adaptable to a wide range of laser types and power levels. The theory of the method is discussed, and the performance of a prototype system, used with a CO laser and having a dynamic range of >10(5), is presented.
