On the measurement of photon flux in parametric down-conversion
The European Physical Journal D - Atomic, Molecular and Optical Physics, 2000 We report the measurement of the photons flux produced in parametric down-conversion, performed in photon counting regime with actively quenched silicon avalanche photodiodes as single photon detectors. Measurements are done with the detector in a well defined geometrical and spectral situation. By comparison of the experimental data with the theory, a

Parametric-Down Conversion of X-rays into the Optical Regime [PDF]
Conference on Lasers and Electro-Optics, 2017 We report the observation of parametrically down-converted x-ray signal photons at photon energies that correspond to idler photons at optical wavelengths. The count-rate dependence on the angles of the input beam and of the detector and on the slit sizes agrees with theory within the experimental uncertainties.

Sech-squared Pockels solitons in the microresonator parametric down-conversion
, 2021 We present an explicit sech-squared-soliton solution associated with the optical Pockels effect, achieved through the generation of the frequency combs via parametric down-conversion in optical microresonators with quadratic nonlinearity.

Entanglement, Complementarity, and Vacuum Fields in Spontaneous Parametric Down-Conversion
Atoms, 2019 Using two crystals for spontaneous parametric down-conversion in a parallel setup, we observe two-photon interference with high visibility. The high visibility is consistent with complementarity and the absence of which-path information. The observations
