The first terahertz quantum-cascade laser (THz QCL) made in Russia in collaboration between SPbAU RAS and IUHFSE RAS was demonstrated. The design of the active region of THz QCL based on the three quantum wells with the resonant-phonon depopulation scheme was proposed. A molecular beam epitaxy growth of the multilayer GaAs/AlGaAs heterostructures (228 cascades) was developed. Studies of I-V and of the emission characteristics of the fabricated THz QCL conducted in IPM RAS confirmed the nature of the stimulated emission in the test devices. The postgrowth processing was tested on the heterostructures from Trion Technology Co. (USA).
