Ceramic Laser Reflector for Pump Chamber

Introductions

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

Prime Features

1. Surfaces can be sealed and coated with a solarization-resistant glaze to give high bulk refectivity

2. 97% reflectance efficiency at 600-1000nm

3. Reflectance efficiency exceeds 95% across the wavelength range 400-1200nm (see curve)

4. Controlled porosity

5. Good thermal conductivity

6. High electrical resistivity

Physical properties

1. Color: White

2. Bulk density (fired), Mg/m3 :3.1

3. Porosity (apparent), % nominal :22

4. Flexural strength (ASTM C1161, 3-point), MPa :170

5. Thermal expansion coefficient

200-500C, 10-6/C 7.9

200-1000C, 10-6/C 9.0

Typical 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
