| contents | We develop a theoretical model for a tunable coherent terahertz radiation source based on the long-lived Bose condensate of photons. In the device we propose, the original photon pumping is performed incoherently by a blackbody radiation emitter. The photons thus produced Bose-condense by the inelastic relaxation on a two-dimensional electron gas in a perpendicular magnetostatic field. The process involves neither population inversion nor light wave amplification the standard laser sources are built on. The coherence and tunability of the light emitted by such a photon condensate are provided and supported by the discrete spectrum of the electron gas in the quantizing magnetic field. The device is a compact-size semiconductor crystal. We propose the design and perform the realistic calculations of the physical properties and limiting factors for the terahertz photon Bose-condensate resonator. We show that our terahertz source can deliver the highly coherent light emission in the frequency range of 3-30 THz for the magnetic field induction of the order of 2 T, with the upper emission frequency limit adjustable by the strength of the magnetic field applied. |
