Session 1: Laser Interactions with Glasses

The field of light interaction with matter has attracted increased attention with advances in ultrashort pulse lasers and high-power fiber lasers, and the need to design and fabricate structures for use in low loss applications. New phenomena have been observed and new applications have been developed whereby lasers are employed in diverse areas such as cutting, welding and engraving of glass, fabrication of waveguides, gratings and micro-channels, etc. inside the bulk of glass, and most recently, 3D printing through additive or subtractive laser-assisted processing. Lasers have been shown to be versatile in other applications of phase change, whereby glass or amorphous media are ‘converted’ in a controlled way to crystalline or composites (glass ceramics). These advances have been realized in optical phase change materials, laser induced crystallization such as seen in the fabrication of active single crystal architecture, strengthening of glass and other applications where a knowledge of not only the material, but the light/matter interaction mechanism is required.

This session will focus on the most recent and advanced issues pertaining to the science and applications of laser-glass interactions, such as laser irradiation effects, compositional and structural changes, dynamics and mechanisms of laser-induced modifications.
