Abstract
An incident radiation absorber having a plurality of cooled panels which provide for absorption steps for radiation reflected from the beam oscillation region of a laser. The panels are arranged in such an assembly array as to form a compact absorption system. Radiation absorbed is dissipated and reduced in intensity by the precisely set angles, surface coatings and cooling so as to render the radiation leaving the system as controlled, reduced to a harmless 21/2% and directed away from the oscillation region of the laser.
