中文摘要	absolute measurement of detector quantum efficiency using optical parametric down-conversion has been extensively studied for the case of a continuous wave pump. in this paper, we have used the temporally and spatially correlated properties of the down-converted photon pairs generated in a nonlinear crystal pumped by a femtosecond laser pulse to perform an absolute measurement of detector quantum efficiency. the measured detector quantum efficiency is in excellent agreement with the measured value in the conventional way. a lens with a long focal length was adopted for efficiently increasing the intensity of the down-conversion entangled photon source.
