WebOct 20, 2000 · Modulation Instability (MI) is a process that appears in most nonlinear wave systems. Because of MI, small amplitude and phase perturbations (from noise) grow rapidly under the combined effects of nonlinearity and diffraction (or dispersion, in the temporal domain). As a result, a broad optical beam [or a quasi–continuous wave (quasi-CW ... WebApr 4, 2024 · Jitter radiation is incoherent emission in general (Medvedev 2000). However, in this paper, we suggest that the jitter radiation in our model is coherent. We provide two reasons. First, kinetic turbulence provides a perturbation field to jitter radiation in our scenario, and the jitter radiation can have emission in a small coherent length scale.
