WebMay 15, 2003 · When the incoherent wave exhibits homogeneous fluctuations, the relevant kinetic equation is the wave turbulence (Hasselmann) equation. It describes wave … WebSep 17, 2013 · An approach is presented for numerically simulating incoherent imaging using coherent wave optics propagation methods. The approach employs averaging of irradiance from uncorrelated coherent waves to produce incoherent results. WebAug 8, 2024 · We revisit the mechanisms underlying the process of spectral broadening of incoherent optical waves propagating in nonlinear media on the basis of nonequilibrium thermodynamic considerations. A simple analysis reveals that a prerequisite for the existence of a significant spectral broadening of the waves is that the linear part of the … inches per feet
