Ruby
Ruby laser material combines excellent physical and optical properties with ideal laser performance characteristics. The thermal conductivity of the
aluminium oxide host is superior to all other solid state laser host. It is very hard, chemically inert, and can be fabricated and polished to demanding
specifications.
Commercial lamps effectively pump Ruby's broad absorption bands to produce a 694.3 nm output, characterised by a long fluorescent lifetime and
large energy storage and gain.
