Abstract

Two-photon entangled states generated by the nonlinear optical process of spontaneous parametric downconversion (SPDC) have found extensive use in recent years for testing the basic foundations of quantum theory. At the same time, the area of ultrafast femtosecond optics using conventional lasers has blossomed enormously, and much has been learned about physical and biological systems using this tool. We have carried out a set of experimental and theoretical studies at the crossroads of these two fields.
