         Products             Ceramic Reflector  (Ceramic Diffuse Reflector)
 
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 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.

 

Specifications

Production capabilities

  • Components up to 250mm long and 80mm wide/diameter manufactured as standard

  • Larger components manufactured to development contracts

  • One-piece or split-cavity designs

  • Prototype, batch and volume production.

As far as the IPL parts are concerned, there are many “variation on the same theme” in order words the angle may be slightly different, length could vary and some parts have no holes, others have several holes.  Parts could also be glazed or un-glazed.  We can make any parts and we could adapt the drawings to customer’s requirements’.
