Ceramic Reflectors for Solid State Laser Pumping Cavities and High Intensity lamps- Morgan Advanced

Solid-state lasers include all optically pumped lasers in which the
gain medium is a solid at room temperature.

Customer requirements will differ dependant upon the type of laser,
laser rod, source radiation (and source power) being employed and
the particular end use of the laser. All, however, require a high
reflectance material to form the pumping chamber cavity surrounding
the laser rod and lamp. The efficiency in transfer of radiation from the
source to the laser rod (referred to as optical coupling) determines to
a large extent the overall efficiency of the laser system. The cavity
walls must therefore have a high reflectivity at the absorption bands
of the laser material.

Ceramic reflectors supplied by Morgan Advanced Ceramics (MAC)
work particularly well in Ruby and Nd:YAG laser pumping chambers
and can be a highly cost effective alternative to metal coated
reflectors. They are also used extensively as reflectors in housings
for high intensity lamps. The reflectors are manufactured from Sintox
AL, a high purity, porous (99.7% Al2O3) material, that:

resists chemical attack
has high strength
has a high reflectivity over a broad wavelength band
has good thermal conductivity and
excellent dimensional and electrical stability at all operating
temperatures.
