摘要：

in order to increase the damage threshold of metal mirrors we propose to create a special structure on the surface of the mirrors ("photonic surface"). This structure must have the period about lambda/2 and will suppress propagation of surface plasmons with the frequency omega(0)=2 pi c/lambda along the surface. This structure will also slightly increase the heat removal from the mirror's surface by the excitation of the thermostimulated plasmon emission from the surface. Thr heat removal from the surface is estimated and possible implementation of this approach For use with CO2-lasers (lambda=10.6 mu m) and Nd-YAG-lasers (lambda=1.06 mu m) is analyzed.
