Two nobel radiation process are reviewed. One is a DARC (Dc to Ac Radiation Convertor) and the other is a superradiance process. DARC can emit the radiation from a static electric field via the interaction between the field and a laser created ionization front. The frequency of the radiation mainly depends on the geometry of the DARC structure. The superradiance is the stimulated emission from spatially localized ensembles of electrons and is promising method of generating powerful ultrashort electromagnetic pulses. Here, radiation from a thin electron layer is reviewed as a simple model of superradiance.
