Partial nonlinear reciprocity breaking through ultrafast dynamics in a random photonic medium
, 2012 We demonstrate that ultrafast nonlinear dynamics gives rise to reciprocity breaking in a random photonic medium. Reciprocity breaking is observed via the suppression of coherent backscattering, a manifestation of weak localization of light. The effect is

Ultrafast Laser Welding of Silicon
Advanced Photonics Research, 2023 While ultrafast laser welding is an appealing technique for bonding transparent workpieces, it is not applicable for joining silicon samples due to nonlinear propagation effects which dramatically diminish the possible energy deposition at the interface.
