Ceramic Laser Reflector for Pump Chamber

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
