Abstract

We describe the interaction of an electromagnetic wave with an electron density perturbation oscillating with relativistic velocities inside a cavity. Using a linear mode coupling theory, we calculate analytically the full spectral content of the radiation remaining inside the cavity. Moreover, it is shown that the coupling mechanism can generate a broad supercontinuum spectrum, by energy transfer between the cavity modes via linear mode coupling.
