Generation of ultrashort pulses by two-component superradiance media

Anatolii V Andreev, P. V. Polevoy

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.

Superradiance of two-component media

A V Andreev, P V Polevoy

The superradiance (SR) phenomenon is considered for the case of a medium consisting of two resonant components. It is shown that the dynamics of emission in this case differs essentially from that for a monocomponent medium. The use of a two-component medium results in a substantial weakness in the requirements for duration of the pumping pulse. The peak pulse intensity of superradiance for the case of a two-component medium can exceed that for each of the components separately. By varying the active medium length and concentration of components we can control the spatiotemporal dynamics of emission. This enables us to transform the broadened pumping pulse of a lower intensity into the ultrashort high intensity pulse of SR.
