Introduction

Ceramic laser reflectors are high reflectance cavities used in solid state and CO2 laser systems. It is made of high purity 99% porous alumina ceramic and sintered at high temperatures to achieve a controlled porosity.

Our range of custom ceramic reflectors offer significant advantages and improvements over those made with materials such as metal and polymer, it works particularly well in Ruby and Nd:YAG laser pumping chambers and is used extensively for long-life laser reflectors.

Physical Properties：

  • Color: White
  • Bulk density (fired), Mg/m3:3.1
  • Porosity (apparent), % nominal:22
  • Flexural strength (ASTM C1161, 3-point), MPa :170
  • Thermal expansion coefficient 200-500C, 10-6/C 7.9 200-1000C, 10-6/C 9.0

 

Features:

  • Surfaces can be sealed and coated with a solarization-resistant glaze to give high bulk reflectivity
  • 97.8% reflectance efficiency at 1000nm
  • Reflectance efficiency exceeds 96% across the wavelength range 500-2000nm(see curve)
  • Controlled porosity
  • Good thermal conductivity
  • High electrical resistivity

Applications:

  1. 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.
  2. Layered and segmented pumping chambers for diode pumped lasers.
  3. Intense Pulse Light (IPL) applications for cosmetic surgery.
