    • The proposed method for generating laser radiation includes creation of an excitation flux for the active material of a hollow cylindrical element, continuous and uniform excitation of said material, providing for a plane-parallel electromagnetic field having in its cross-section the form of a ring generating an annular laser radiation at the frequencies of the induced radiation of the active material, and suppression of non-axial components of the laser radiation. At the same time in the resonating annular electromagnetic field the longitudinal modes are suppressed, excepting ''TEMoo'' modes at the frequencies of the induced radiation, by choosing the width of the resonating field ring equal to or exceeding the threefold geometric mean of the length of said field and by choosing the maximum wave length of the mode ''TEMoo'' from energetically significant modes ''TEMoo'' at the ratio of the internal diameter (D1) to the external diameter (D2) of said ring equal to or exceeding 0.09. In the proposed laser device the wall (9) of a hollow cylindrical element (2) of the active material of a resonator (7) has the thickness equal to or exceeding the threefold geometric mean of the optical length (L) of the resonator (7) and of the maximum wave length of the mode ''TEMoo" at the ratio of the internal diameter (D1) of the hollow element (2) to its external diameter (D2) equal to or exceeding 0.09. The source of the excitation flux consists of a continuous pumping flow-discharge lamp (8, 13) shaped as an annular hollow cylinder located coaxially to the cylindrical element (2).
