Production and propagation of Hermite–sinusoidal-Gaussian laser beams

摘要: Hermite–sinusoidal-Gaussian solutions to the wave equation have recently been obtained. In limit of large Hermite–Gaussian beam size, sinusoidal factors are dominant and reduce conventional modes a rectangular waveguide. opposite beams familiar form. The propagation these is examined in detail, resonators designed that will produce them. As an example, special resonator hyperbolic-sine-Gaussian beams. This ring contains hyperbolic-cosine-Gaussian apodized aperture. mode has finite energy perturbation stable.
