Morgan Advanced Ceramics Sintox ™AL Aluminum Oxide Ceramic
Categories: Ceramic; Oxide; Aluminum Oxide

Material Notes: High purity porous alumina ceramic of 99.7% Al2O3 content, used extensively for long-life laser reflectors. This material is sintered at high temperatures to achieve a controlled porosity.

Prime Features:

  • 98.0% reflectance efficiency at 1064nm
  • Reflectance efficiency exceeds 96% across the wavelength range 500-2000nm.
  • Controlled porosity.
  • Good thermal conductivity.
  • High electrical resistivity.
  • Highly cost effective alternative to metal coated reflectors .
Typical Applications:
  • Pumping chambers for flash lamp and continuous wave lasers using media such as Nd:YAG lasers, Alexendrite — low to high power, single or multiple lamp designs used for welding, cutting, marking and in medical lasers.
  • Layered and segmented pumping chambers for diode pumped lasers
  • Intense Pulse Light (IPL) applications for cosmetic surgery
Production Capabilities:
  • Components up to 250mm long and 80mm wide/diameter manufactured as standard
  • Larger components manufactured to development contracts.
  • One-piece or split-cavity designs
  • Surfaces can be sealed and coated with a solarization-resistant glaze to give high bulk strength of the part
  • Glazing / Coatings available include on Standard (“Sintox AL - GSO”) glaze
  • UV wavelength cut-off glaze (“Sintox AL - GSY”) which cuts off Wavelength upto 500nm . Advantage of this is that it reduces heating of the components.
