WebAug 5, 2024 · Using the Wigner function we evaluate the purity of the two-photon state, showing that for a TGSM beam it is proportional to the normalized transverse coherence of the pump beam. We also considered the Gaussian approximation to the phase matching function, showing that it corresponds to a loss of purity of the two-photon state.
