Abstract
An apparatus includes a base that includes a raised surface and a first opening through the raised surface. The apparatus also includes a cover configured to be coupled to the base in order to form a cavity, where the cover includes a second opening through the cover. The raised surface is configured to allow passage of a first portion of optical energy through the first opening and to reflect a second portion of the optical energy. Portions of the cover and the base surrounding the cavity are configured to absorb the reflected second portion of the optical energy. The base may further include one or more baffles positioned around the raised surface, and/or the cover may further include one or more baffles positioned around the second opening.

An apparatus comprising:
- a base comprising a raised surface and a first opening through the raised surface;
- and
- a cover configured to be coupled to the base in order to form a cavity, the cover comprising a second opening through the cover;
- wherein the raised surface is configured to allow passage of a first portion of optical energy through the first opening and to reflect a second portion of the optical energy;
- and
- wherein portions of the cover and the base surrounding the cavity are configured to absorb the reflected second portion of the optical energy.
A system comprising:
- a laser configured to generate an optical beam;
- and
- a beam scraper and power dump configured to scrape the optical beam, the beam scraper and power dump comprising:
- a base comprising a raised surface and a first opening through the raised surface;
- and
- a cover configured to be coupled to the base in order to form a cavity, the cover comprising a second opening through the cover;
- wherein the raised surface is configured to allow passage of a first portion of the optical beam through the first opening and to reflect a second portion of the optical beam;
- and
- wherein portions of the cover and the base surrounding the cavity are configured to absorb the reflected second portion of the optical beam.
A method comprising:
- passing an optical beam through a cover of a beam scraper and power dump;
- passing a first portion of the optical beam through an opening in a raised surface located on a base of the beam scraper and power dump;
- reflecting a second portion of the optical beam from the raised surface into a cavity of the beam scraper and power dump;
- and
- absorbing the reflected second portion of the optical beam using portions of the cover and the base surrounding the cavity.
