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 ...

Two-photon indirect absorption in GaSe
Journal of Physics: Conference Series, 2008 Two-photon absorption (TPA) in GaSe is detected in the narrow (about kT) spectral range above the indirect exciton energy for E⊥c light polarization. The appearance of TPA enhancement within narrow spectral region links to the resonant Raman scattering and anti-Stockes photoluminescence previously identified in GaSe. Extracted TPA coefficient is of the

Two-photon-absorption properties of pyrene-based dipolar D-π-A fluorophores [PDF]
, 2018 Two‐photon absorption (TPA) properties of pyrene‐based derivatives are rare as a result of the limited number of controllable synthetic methods to prepare them.

Two-photon absorption of Tl1-xIn1-xSnxSe2 nanocrystallites
EPJ Web of Conferences, 2017 Novel materials for the infrared two-photon absorption — Tl1-xIn1-xSnxSe2 single crystals (x = 0.1,0.2) were grown. Two-photon absorption (TPA) was studied at CO2 laser wave-length 9.4μm with pulse duration 1μs.

Molecular Oncology, EarlyView.We have established a humanized orthotopic patient‐derived xenograft (Hu‐oPDX) mouse model of high‐grade serous ovarian cancer (HGSOC) that recapitulates human tumor–immune interactions. Using combined anti‐PD‐L1/anti‐CD73 immunotherapy, we demonstrate the model's improved biological relevance and enhanced translational value for preclinical ...
