Writing on glass and silica indicates novel direction for chiral optical property tailoring

From fundamental physics of light-matter interaction to fabrication of targeted optical properties in highly complex optical engineering, the femtosecond (fs) laser plays a crucial role in laser manufacturing. Ultrashort light pulses can precisely deposit light energy in a given transparent material volume by controllable focusing conditions. Nonlinear absorption of high-density photon energy leads to the creation of free electrons plasma within a few fs, before the electron-phonon energy transf...
