ABSTRACT

An optically pumped submillimeter laser on a basis of the quasioptical waveguide resonator with mode selector is investigated experimentally. It is shown that the proposed method for the selection of transverse modes by an iris diaphragm on the plane mirror of a system of deflecting mirrors allows one to ensure the effective suppression of higher oscillation mode when operating of a laser in a wide spectral range.
