Description
An increase in the radiation power of THz sources creates the need for the development of new optics operating with it. Here, we propose and realize the fabrication of silicon and diamond diffractive lenses with a continuous profile by the method of direct and indirect laser ablation, respectively. The fabricated lenses were tested with a free-electron laser at the wavelength of 141 µm and demonstrated high diffraction efficiency and a good agreement with the theoretical prediction. The work was supported by RFBR grant 18-32-20226
