    "abstract": "We propose a scheme for generation of continuous-wave THz radiation. The\nscheme requires a medium where three discrete states in a $\\Lambda $\nconfiguration can be selected, with the THz-frequency transition between the\ntwo lower metastable states. We consider the propagation of three-frequency\ncontinuous-wave electromagnetic (e.m.) radiation through a $\\Lambda $ medium.\nUnder resonant excitation, the medium absorption can be strongly reduced due to\nquantum interference of transitions, while the nonlinear susceptibility is\nenhanced. This leads to very efficient energy transfer between the e.m. waves\nproviding a possibility for THz generation. We demonstrate that the photon\nconversion efficiency is approaching unity in this technique.",
