GSY Yellow Reflector Glaze
Dec 2010

WINDSOR, Enlgand, Dec. 9, 2010 — To increase the efficiency of laser systems, Morgan Technical Ceramics has introduced the GSY visibly yellow reflector glaze for ceramic reflectors that absorbs a much wider range of wavelengths than its clear predecessor, and thereby improves industrial laser performance. The laser cavities do not reach the high temperatures seen previously and consequently require less cooling fluid. The pumps do not have to work as hard as before, which reduces costs. The glaze increases the reliability of the laser system and allows for a significantly extended lifespan.

The glaze improves the efficiency of laser systems by filtering out UV and low wavelengths in laser pumping cavities. It is suited to industrial lasers used in manufacturing and, as a result, end users can benefit from a reduced cost of ownership.

The visible yellow color of the glaze is complementary to the spectral colors violet and indigo and effectively absorbs low wavelengths up to approximately 450 nm.

For a like-for-like design, using the GSY glaze improves output by 5 W, which is approximately 9% higher than with a clear glaze.

The yellow glaze is available as an alternative option to the company’s highly reflective GSO clear glaze. Both seal ceramic reflectors against the ingress of cooling fluids that may alter the refractive index, introduce impurities, and reduce reflectance and operating efficiency.

The robust laser reflectors are produced from a high-performance alumina-based ceramic. They have high strength, good thermal conductivity, and good dimensional and electrical stability at all operating temperatures. They are chemical-resistant and have a high reflectivity over a broad wavelength band. Ceramic reflectors are a cost-effective alternative to metal-coated reflectors.
