Claim 0:
1. An apparatus comprising:
an ultraviolet laser; and
at least one reflective mirror adapted to reflect a laser beam generated from the ultraviolet laser;
wherein the at least one reflective mirror comprises a mirror substrate,
wherein the mirror substrate is made from silicon carbide or an aluminum metal matrix composite, and has:
(i) an optical Figure of Merit (FoM) resonant frequency value of at least 6 relative to a fused-quartz substrate;
(ii) an optical FoM self-weight deflection value of less than 0.030 relative to a fused-quartz substrate;
(iii) an optical FoM steady-state thermal distortion coefficient value of less than 0.350 relative to a fused-quartz substrate; and
(iv) an optical FoM transient thermal distortion coefficient value of less than 0.600 relative to a fused-quartz substrate.
