| 摘要 |
The present invention aims to allow the as complete as possible absorption of a light beam having a power or energy greater than those which can be absorbed without damage by known absorbers. The incident beam R1, R2, R3 to be absorbed is received axially on a mirror 10 whose shape is calculated so that the power of the reflected beam R'1, R'2, R'3 is uniformly distributed over a cooled coaxial cylinder absorption wall 12. The invention applies especially to the manufacture and use of high-power lasers. <IMAGE>
