We consider the possibility of realizing a terahertz spectrometer using the radiation sources based on quantum cascade lasers and the receiving system based on hot-electron bolometers. Precision measurements of the amplitude and phase noise of the quantum cascade lasers in this frequency range are performed. The systems for stabilizing the frequency of the quantum cascade laser are described. The...
