Intense spectrally broad-band twin beams from poled nonlinear crystals
Properties of intense twin beams generated in parametric down-conversion in periodically poled LiNbO(3) crystals and their chirped variants by intense pump fields are analyzed along the model of intense parametric down-conversion that allows for pump depletion and uses the dual spatio-spectral Schmi...

| Sumario: | Properties of intense twin beams generated in parametric down-conversion in periodically poled LiNbO(3) crystals and their chirped variants by intense pump fields are analyzed along the model of intense parametric down-conversion that allows for pump depletion and uses the dual spatio-spectral Schmidt modes. Spectral and spatial intensity auto- and cross-correlation functions are determined as they depend on the pump power. Temporal correlations in intense twin beams at the fs time scale are investigated using the Hong-Ou-Mandel interferometer and the process of sum-frequency generation. |
