Oven-less process for annealing glass coatings

Article Type: Materials From: Aircraft Engineering and Aerospace Technology: An International Journal, Volume 81, Issue 4

Laser Photonics, a major company in developing high-tech solid state and CO₂ laser systems for marking, cutting and engraving applications, announced today the development of a new laser-based oven-less process for annealing glass coatings.

Traditionally, to anneal a coating on glass, the coating was applied to the glass, baked at 600°C, and then cooled for 3-4 h. Using this new oven-less annealing process developed by Laser Photonics, the coating is applied to the glass and then a laser beam is swept over the surface to anneal. The heat-affected zone is limited and the material can be handled relatively soon after the annealing is complete. Using this new process, the light transmission efficiency is said to be increased by 35 per cent. Additionally, the process lowers the electrical surface resistance, prevents de-lamination and performs recrystalization of amorphous silicon. Glass that has been coated and annealed is used for such things as solar panels.
