Today, a new research project has been announced that could revolutionize the way we fabricate fused silica optics for high power laser applications. Researchers at the University of California, Berkeley have created a process which can produce large-scale fused silica optics with a high degree of accuracy and control. The process involves laser-based fabrication, which can create complex shapes with a high degree of precision, and allows for the creation of optics with minimal surface roughness and low scattering losses. This breakthrough promises to significantly reduce the costs associated with producing high-power laser optics, making them much more accessible for a wide range of applications.
