Ceramic Reflector features:
- Compared to metal reflectors, ceramic units offer higher reflectivity and therefore enhanced laser power
- Surfaces can be sealed and coated with a solarization-resistant glaze to give high bulk reflectivity
- Resists chemical attack
- Controlled porosity
- Has high strength
- Good thermal conductivity
- High electrical resistivity
We can machine or grind ceramic reflectors against the customer's drawing. Quantities range from prototype to production quantities. Glazing protects the surface in preventing adhesion of impurities and primarily ensures leak tightness of the reflectors.

Frequently Asked Questions
Why choose porous alumina for laser reflectors? How does a glazed ceramic surface enhance pumping efficiency?
High-purity 99% porous alumina ceramic offers superior diffuse reflectivity compared to metallic reflectors, significantly enhancing pump chamber efficiency in flash lamp and diode-pumped solid-state (DPSS) lasers. Applying a solarization-resistant glaze seals the porous microstructure, providing high chemical resistance, preventing coolant leakage, and blocking impurity buildup for extended operational life in high-power continuous-wave (CW) systems.
Can I order custom ceramic reflectors for medical and industrial lasers? How to get a quote from the manufacturer?
Yes, as a precision technical ceramic manufacturer, INNOVACERA produces custom glazed and unglazed ceramic laser reflectors, pump chambers, and laser cavity inserts. We machine components from single prototypes to mass production based on customer specifications. To receive a competitive price quote, please share your CAD drawings, required dimensions, cooling channel configurations, and glazing specifications.
