This paper presents experimental results on the formation of given laser modes from an illuminating Gaussian beam of the terahertz Novosibirsk free electron laser at a wavelength of 141 μm. Binary silicon diffractive optical elements were applied. The experimental results obtained are in good agreement with the results of computer simulation.
