Incoherent perturbation
WebIn class we found the transition rate to go from a to b, under incoherent perturbation, but with a fixed polarization, was: a atom with an electron of charge q For radiation from all directions and polarization show: Rb→a = 31 ε0ℏ2π q2∣ ψb∣r∣ψa ∣2 ρ(ω0)[1] ρ(ω0) is the energy density of the field per unit frequency. Previous question Next question 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 …
