Abstract : Ultrafast laser photoinscription has become a viable method for 3D processing of dielectric materials based on nonlinear energy confinement. As the processing results depend on the spatio-temporal character of interaction, we report on the use of adaptive self-improving optics in spatio-temporal domains for upgrading laser-induced refractive index engineering with respect to the quality of the structural change and the time-effectiveness of interaction. New laser-matter synergies are created and concepts of parallel processing and wavefront engineering are explored. Additionally, taking advantage on laser-induced self-arrangement on the nanoscale we design polarization sensitive devices and indicate particular light propagation properties in 3D structures.
