Femtosecond-irradiation-induced refractive-index changes and channel waveguiding in bulk Ti3+: Sapphire

René Salathé, Christian Depeursinge, Tristan Colomb

We have employed femtosecond laser writing in order to induce refractive-index changes and waveguides in Ti3+-doped sapphire. Doping the sapphire crystal with an appropriate ion significantly reduces the threshold for creating structural changes, thus enab ...
