Developed for high-energy pulsed Q-switching infrared laser applications, a new, high-absorption samarium oxide glaze from Morgan Advanced Materials (Windsor, UK) means it is now able to offer three grades of glaze for laser systems. The samarium glaze absorbs radiation at the Nd-YAG lasing wavelength of 1,064 nm, and its further transitions near 940 nm, 1,120 nm, 1,320 nm, and 1,440 nm. A significant amount of fluorescent radiation at the lasing wavelength escapes laterally from the laser rod into the surrounding pumping cavity. Morgan’s high- absorption samarium oxide glaze is formulated through the controlled addition of dopant to create optimum reflectance properties. Features include:
- Typical 98% reflectance in the desired wavelength range.
- A glaze that matches yellow (GSY) and clear (GSO) glazes between 700 nm and 900 nm.
- An optimum reflectance capability across the range of three glazes that spans wavelengths of around 580 nm up to 2,000 nm.
