Ceramic Reflectors

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


A porous alumina ceramic of99.7% Al2O3content, used extensively for long-life laser reflectors. This material is sintered at high temperatures to achieve a controlled porosity.

Prime features

Typical applications   Pumping chambers for Nd:YAG lasers — low to high power, 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.


Production capabilities

Physical properties*

Reflectance curve
