Abstract: Experimental results on forming pre-given laser modes from an illuminating Gaussian beam of a terahertz Novosibirsk Free Electron Laser (NovoFEL) at the wavelength of 141 mm by use of binary silicon diffractive optical elements are presented. The experimental results are in good agreement with the results of computer simulation.

Keywords: Diffractive optics, Free-electron lasers, terahertz radiation, Lasers, single-mode.
