Abstract
A calculation of the absorptance A of aluminum in the vacuum ultraviolet (vuv) indicates that the lowest values measured to date, A=0.08−0.10 for h/ω=3−12 eV, are very near the intrinsic limit. Operating at low temperature, purifying the metal, or improving the surface are not expected to decrease A by more than ∼0.02, and metallic reflectors better than aluminum are not likely to be found. Thus, values of A<0.06 for metals without reflection−enhancing coatings are not likely to be attained in the vuv, and lasers with such reflectors will continue to be limited by the performance of the reflectors.This publication has 17 references indexed in Scilit:
