DOCERAM Ultimate Ceramic Co.,Ltd.

Company Description

Ceramic reflectors are recently used in laser pump chambers. Its main advantages are long life time.

Description

A 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

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

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

Typical applications

Pumping chambers for ND: YAG lasers _ low to high poDOCERAM Ultimate Ceramic Co.,Ltd.r, single or multiple lamp designs. Pumping chamber reflectors of this material are virtually indestructible, and prove a highly cost effective alternative to metal coated types.
