Abstract
It relates to a high-power laser attenuator wherein laser is incident into an attenuator housing through a lens barrel; a ½ wave plate, a first lens and a second lens are arranged in sequence on an incident light path along a laser incident direction; the ½ wave plate can rotate around the incident light path, and normal lines of incident planes of the two lenses and the incident light axis are set to form a Brewster angle; a laser absorber assembly is arranged in a reflected light path of the first lens.
