Generation of ultrashort pulses by two-component superradiance media

A method is proposed for substantially reducing the length of superradiance pulses and increasing their intensity. The idea is to introduce an additional coherent resonant component, with a higher Rabi frequency, in a superradiance medium. The superradiance intensity of a two-component medium of this sort can be substantially higher than that of either component individually. The pump pulse can be several orders of magnitude longer than the generation pulse. The parameters of the generation pulse are controlled by varying the length and composition of the active medium.
