The development of high-index glass contour cutting technology has led to significant advancements in both technical and aesthetic aspects, which are crucial for expanding the use of augmented reality (AR) applications in various markets. In this attached Application Note, we showcase a Spectra-Physics IceFyre® infrared picosecond laser with advanced burst mode pulse shaping capability for achieving high-quality, small-radius contour cutting of high-index glass. Optimizing average laser power, intra-burst sub-pulse relative energy, and sub-pulse spacing, we achieved an edge roughness of 0.4 µm Ra while maintaining a consistent modification depth of around 500 µm in 0.7-mm thick glass. Moreover, we achieved smooth corner radiuses of 0.5 mm by proportionally adjusting the laser’s pulse frequency to match the motion system's overall capabilities. The laser system produced straight-line cuts at a speed of 200 mm/s, which could be increased to more than 1.6 m/s by utilizing the entire available laser power. Additionally, smooth and small corner radiuses of 0.5 mm were obtained by further taking advantage of the laser’s flexibility in pulse output to match the performance of any motion system it interfaces to.
