Femtosecond laser direct writing in SiO2‐Al2O3 binary glasses and thermal stability of Type II permanent modifications

We investigate the potential of fabricating thermally stable refractive index contrasts using femtosecond (fs) near‐infrared (IR) radiation in aluminosilicate glasses. A set of pure SiO2‐Al2O3 glasses are manufactured, characterized (density and Raman), and investigated after being irradiated by fs...
