White Ceramic Reflector Information
Product Description
The ceramic reflector green body is made of 99% Al2O3, and the green body is fired at an appropriate temperature to retain proper porosity and proper green strength. The surface of the reflector is fully coated with high-reflectivity ceramic glaze. Compared with the gold-plated reflector, the biggest advantage lies in its extremely long service life and diffuse reflection.

Diffusive ceramic reflectors for Nd:YAG laserCeramic reflector typical application is 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. 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. Ceramic reflectors also can use many other kinds of lasers, such as for Diode-pumped Solid-state Lasers.
Customized Alumina Ceramic Laser Reflector For Medical Equipment or Skin Care

Our reflectors can be glazed both inside the cavity and around the outer edges using a highly reflective glaze that seals the
ceramic against ingress of cooling fluids that may alter the refractive index, introduce impurities and reduce reflectance and
efficiencies.

Main features:
1. Dimensional tolerance in height direction can achieve tolerance ≤1.0mm, other dimensional tolerances can reach ≤0.5mm
2. The surface is fully glazed to achieve maximum reflectivity and easy to clean
3. The reflectivity reaches 97% at the wavelength of 600-1000nm
4. The reflectivity exceeds 95% in the wavelength range of 380-1100nm
5. The body has proper porous and high strength characteristics

Advantage:
Simple structure: Ceramics can be easily shaped according to specific requirements to meet various usage needs.
Uniform pump distribution: They are an ideal material for diffuse reflection cavities, ensuring good pump uniformity.
High pump conversion efficiency: Achieving higher ceramic purity and enamel quality on the inner cavity can lead to improved pump conversion efficiency.


Yellow Ceramic Reflectors
The yellow-glazed ceramic laser reflector cuts off wavelengths in the UV range which reduces the amount of heat generated in the laser head. It exhibits high reflectivity in the main absorption band of the solid-state laser, and at the same time exhibits the function of reducing the reflectivity in the ineffective absorption band. As a contrast, the diffuse reflective ceramic condenser cavity has high reflectivity in the non-absorptive ultraviolet band of the laser crystal, but it cannot effectively filter out the ultraviolet light that produces a harmful color center to the laser crystal. The highly reflective, UV-absorbing yellow glazed ceramic glaze can obviously improve the shortcomings of ordinary ceramic laser reflector. It has the characteristics of strong laser radiation resistance, high insulation, corrosion resistance, easy cleaning, and UV absorption. It extends the service life, reduces cooling requirements and in some cases reduces operating costs.
