Entangled two-photon absorption spectroscopy by Schlawin, F, Dorfman, K, Mukamel, S

“…This is because between the two absorption events in entangled two-photon absorption, the light and material system are entangled. …”

Study of two-photon absorption and optical limiting by Bal Ram Ghimire

“…It was investigated that two photons absorption depletes the transmitted beam but carrier defocusing spreads the beam in space and hence density is reduced. …”

Two-photon absorption and the design of two-photon dyes. by Pawlicki, M, Collins, H, Denning, R, Anderson, H

“…These applications have generated a demand for new dyes with high two-photon absorption cross-sections. This Review introduces the theory of two-photon absorption, surveys the wide range of potential applications, and highlights emerging structure-property correlations that can serve as guidelines for the development of efficient two-photon dyes.…”

Witnessing entangled two-photon absorption via quantum interferometry by Áulide Martínez-Tapia, Samuel Corona-Aquino, Freiman Triana-Arango, Chenglong You, Rui-Bo Jin, Omar S. Magaña-Loaiza, Shi-Hai Dong, Alfred B. U’Ren, Roberto de J. León-Montiel

“…Recent investigations have suggested that the use of non-classical states of light, such as entangled photon pairs, may open new and exciting avenues in experimental two-photon absorption spectroscopy. Despite several experimental studies of entangled two-photon absorption (eTPA), there is still a heated debate on whether eTPA has truly been observed. …”

Tuning two-photon absorption cross-sections for triphenylamine derivatives by Fang, Zhen, Webster, Richard David, Samoc, Marek, Lai, Yee-Hing

“…The one-photon spectroscopies of bridged triphenylamine molecules show considerable extended conjugation relative to their triphenylamine counterparts, leading to enhanced two-photon absorption (TPA) cross-sections. Various substituents at the scaffold have been prepared and studied. …”
