Quantitative photoacoustic imaging of two-photon absorption [PDF]
Journal of Biomedical Optics, 2018 Two-photon absorption photoacoustic tomography (TP-PAT) is a recent hybrid imaging modality that aims at reconstructing two-photon absorption properties of heterogeneous media from measured ultrasound signals generated by the photoacoustic effect. While there have been extensive experimental studies in recent years to show the great promises of TP-PAT,

Polarization-Entangled Two-Photon Absorption in Inhomogeneously Broadened Ensembles
Frontiers in Physics, 2022 Entangled photons are promising candidates for a variety of novel spectroscopic applications. In this paper, we simulate two-photon absorption (TPA) of entangled photons in a molecular ensemble with inhomogeneous broadening. We compare our results with a

Measurement of transient strain induced by two-photon excitation
Physical Review Research, 2020 By ultrafast x-ray diffraction we quantify the strain from coherent and incoherent phonons generated by one- and two-photon absorption. We investigated the ferrimagnetic insulator bismuth-doped yttrium iron garnet, which is a workhorse for laser-induced ...
