WebDec 3, 2002 · We demonstrate experimentally that a periodic perturbation on a partially spatially incoherent optical beam induces modulation instability that depends strongly on the perturbation periods as well as on the strength of the nonlinearity and the degree of spatial coherence. At a fixed value of the nonlinearity and coherence, the incoherent … WebFeb 7, 2024 · 11th class of 207402, this video serves as part of the class hosted at Chiang Mai University.
