The fluctuation-dissipation theorem (FDT) is an important and elegant tool to determine the intensity of electromagnetic fluctuations in thermal equal-temperature plasmas, a situation often encountered in cosmic and laboratory plasmas. As there is high interest in the fluctuations from stronger damped oscillations, especially aperiodic ones with ωR = 0, the FDT for general oscillations in magnetized plasmas for arbitrary complex frequencies ω=ωR+iΓ is determined. Contrary to weakly damped, the aperiodic fluctuation spectra depend on the Hermitian (instead of the anti-Hermitian) part of the elements of the Maxwell operator. Explicit expressions for the FDT in unmagnetized plasmas are derived in terms of the longitudinal and transverse thermal dispersion functions.
