The Magic of Nonlinear Laser Processing: Shaping Multi-Functional Lab-in-Fiber

By Moez Haque and Peter R. Herman The manipulation of femtosecond laser light inside transparent media can be directed on varying interaction pathways of micro-explosions, photochemistry and self-focusing filamentation to open new directions in creating dense memory storage, three-dimensional (3D) optical circuits, 3D microfluidic networks, and high-speed scribing tracks[1-3]. Our group has been following these […]
