Abstract
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-or-magnitude differences between absorption rates for phase- and amplitude-squeezed beams of the same intensity.
