ABSTRACT:
An attenuating device for attenuating optical power of a light beam, comprises an at least partly absorbing element adapted to receive and attenuate the optical power of the light beam, and a supporting element for supporting on at least one side the at least partly absorbing element. The at least partly absorbing element comprises at least one layer coated or evaporated on the supporting element with an increasing, decreasing, or varying thickness. The supporting element is provided with a material having a crystalline structure to provide compensation to a local heating in the at least partly absorbing element resulting from absorption of the light beam.
