One- and Two-Colour Superradiant Lasting in Magnetized Quantum-Well Heterostructures

Abstract

We study generation of femto second super radiance pulses due to collective recombination of electron-hole (eh) pairs in quantum wells placed in a strong magnetic field oriented perpendicular to the growth plane. Such a super radiant laser can work under the conditions of continuous pumping and at room temperature due to complete quantization of particle motion, maximum possible spectral density of states, high volume density of cyclotron quantum dots, and partial suppression of the intraband scattering. It is shown that two-colour super radiant generation is possible at frequencies resonant to frequencies of the neighboring interband transitions defined by e, h Landau levels.
