Abstract
A method for determining the mode composition a of laser radiation with Bessel mode structure is developed, which includes measurement of intensity distribution and solution of systems of the algebraic equations for amplitudes and phases of partial beams corresponding to different Bessel modes. A method of laser beam quality analysis utilizing a simple optical scheme composed of a telescope, axicon, and microscope is proposed and verified experimentally.
