On the application of Two-Photon Absorption for Laser Fault Injection attacks
Transactions on Cryptographic Hardware and Embedded Systems, 2022 Laser Fault Injection (LFI) is considered to be the most powerful semiinvasive fault injection method for implementation attacks on security devices. In this work we discuss for the first time the application of the nonlinear Two-Photon Absorption (TPA)

Two‐Photon Absorption in Monolayer MXenes [PDF]
Advanced Optical Materials, 2020 AbstractTwo‐photon absorption (2PA) is a nonlinear optical (NLO) effect that typically occurs in a conventional semiconductor whose bandgap is larger than the energy of one excited photon but smaller than the energy of two photons. In this work, the experimental observation of strong 2PA in gapless MXene monolayers is reported.

Entangled Two-Photon Absorption Spectroscopy [PDF]
Accounts of Chemical Research, 2018 The application of quantum states of light such as entangled photons, for example, created by parametric down conversion, has experienced tremendous progress in the almost 40 years since their first experimental realization. Initially, they were employed in the investigation of the foundations of quantum physics, such as the violation of Bell's ...
