Two-photon absorption and the design of two-photon dyes.
Angewandte Chemie - International Edition, 2009 AbstractTwo photons are better than one: This principle applies to a wide range of applications, ranging from engineering to physiology. Recent advances in our understanding of the phenomenon of two‐photon absorption (see picture) and in the design of two‐photon dyes are rapidly increasing the scope of this field.magnified imageTwo‐photon absorption ...

Two‐Photon Absorption in Monolayer MXenes [PDF]
Advanced Optical Materials, 2020 Two‐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

Hot-Band Absorption Can Mimic Entangled Two-Photon Absorption [PDF]
The Journal of Physical Chemistry Letters, 2021 While searching for entangled two-photon absorption in LDS798, we instead observe fluorescence signals originating from hot-band absorption. This process could lead to overestimating entangled two-photon absorption cross sections by several orders of ...

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

Experimental feasibility of molecular two-photon absorption with isolated time-frequency-entangled photon pairs [PDF]
Physical Review Research, 2021 Entangled photon pairs have promised to deliver a substantial quantum advantage for two-photon absorption spectroscopy. However, recent work has challenged the previously reported magnitude of quantum enhancement in two-photon absorption.

Full Quantum Analysis of Two-Photon Absorption Using Two-Photon Wavefunction: Comparison with One-Photon Absorption [PDF]
Journal of the Physical Society of Japan, 2009 For dissipation-free photon-photon interaction at the single photon level, we analyze one-photon transition and two-photon transition induced by photon pairs in three-level atoms using two-photon wavefunctions.
