Abstract-Transverse optical modes for an RF excited Ar-He-Xe laser are studied both experimentally and theoretically. A diffraction model for a waveguide with a nonsaturable gain and refractive index gradients placed between two plane mirrors is formulated. The effects of gain and diffraction index gradients and of diffraction in free space are evaluated for typical experimental conditions. A direct comparison between theoretical mode patterns and experimentally measured ones at distances of 17 and 114 cm from the output mirror demonstrated a satisfactory agreement for various laser wavelengths and gas mixture compositions.

“…where ρ = r/a is the dimensionless waveguide radial coordinate, V m (ρ) is the radial orthonormalized eigen functions for modes of corresponding CDW classes [10], C m are the excitation coefficients of the given modes. Then at an waveguide end in position 2 on distance L from aperture of a flat reflector the expression for this field component can be written down as:…”

A description is given of a method of forming, in a waveguide quasi-optical resonator, non-Gaussian light beams with a uniform intensity distribution. The method is based on the coherent summation of transverse waveguide modes due to change by radius of curvature for one of mirrors. The theoretical model and calculation algorithm for characteristics of the basic mode with the uniform intensity distribution on the resonator output mirror is proposed with use of a method of eigenmodes. The conditions of such mode existence and stability of its characteristics are established by changing the parameters of spherical reflector and the waveguide geometry.

We show analytically that the presence inside an optical cavity of a polarizer and a hard diffracting object, for example, a circular aperture or waveguide, reduces the symmetry of the system from cylindrical to rectangular. As a consequence, patterns with concentric rings of bright or dark spots made up by modes whose azimuthal indexes are not multiples of one another, appear when the zero-field solution becomes unstable. These types of bifurcations are anomalous if the symmetry is cylindrical and therefore indicate the presence of polarization effects induced by diffraction. As an example of this type of system, we investigate numerically the bifurcations of a ring laser with a metallic duct and a polarizer inside the optical cavity.
