Research on Laser Polishing of Optical Glass

Abstract

With the development of photoelectron technology, optical glass and glass ceramic has been used in many different fields. The final machining of this kind of material has very important effect to its future application. In the present study, optical glass and glass ceramic is finished using laser polishing. Laser polishing could eliminate subsurface damage, smooth micro roughness. In certain cases a preheating system should be needed to increase optical glass’ surface integrity. The result shows that laser polishing of optical glass and glass ceramic has higher efficiency compared to conventional optical machining. The flexibility of laser polishing makes it ideal as an enabling technology for the final manufacturing of optical glass and glass ceramic.
