Cooperative two-photon absorption [PDF]
The Journal of Chemical Physics, 1983 It is well known that irradiation with intense laser light can lead to nonlinear absorption processes by individual molecules. However, the mutual interaction between two molecules can lead to cooperative nonlinear processes which result in entirely new features in the absorption spectrum.

Generation of photon pairs using polarization-dependent two-photon absorption [PDF]
, 2003 We propose a new method for generating photon pairs from coherent light using polarization-dependent two-photon absorption. We study the photon statistics of two orthogonally polarized modes by solving a master equation, and show that when we prepare a ...

Two-Photon Absorption of Nonclassical Light [PDF]
Physical Review Letters, 1989 Two-photon absorption of light with nonclassical (squeezed) fluctuations is considered. Several unique effects are predicted for various possible regimes. These include a linear (instead of quadratic) growth of the absorption rate with the light intensity for weak fields, the possibility of a decreasing absorption with increasing intensity, and orders ...

Single Photon Source Using Laser Pulses and Two-Photon Absorption [PDF]
, 2006 We have previously shown that two-photon absorption (TPA) and the quantum Zeno effect can be used to make deterministic quantum logic devices from an otherwise linear optical system.
