Ceramic Laser Reflector for Pump Chamber

Ceramic Reflector

High purity porous alumina ceramic of 99% Al2O3 content, used extensively for long-life Ceramic Laser Reflector. This material is sintered at high temperatures to achieve a controlled porosity.

Prime Features

  • Surfaces can be sealed and coated with a solarization-resistant glaze to give high bulk reflectivity
  • 97% reflectance efficiency at 600-1000nm
  • Reflectance efficiency exceeds 95% across the wavelength range 400-1200nm (see curve)
  • Controlled porosity
  • Good thermal conductivity
  • High electrical resistivity

Physical properties

  • Color: White
  • Bulk density (fired): 3.1 g/cm3
  • Porosity (apparent), nominal: 22%
  • Flexural strength (ASTM C1161, 3-point): 170 MPa
  • Thermal expansion coefficient:
    200-500℃, 7.9*10-6/C
    200-1000℃, 9.0*10-6/C

Typical Applications

  • Pumping chambers for flash lamp and continuous-wave lasers using media such as Nd:YAG lasers,
    Alexandrite — 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
