QUALITY PARAMETERS OF ZERO ORDER BESSEL LIGHT BEAMS
Abstract
The collimated light beam at the output of a semiconductor laser module has been experimentally studied. The intensity distribution in the cross-section of this beam has no axial symmetry of infinite order and varies with the longitudinal coordinate. The spatial intensity distribution in the light fields formed by means of a conical lens (axicon) from the radiation of the semiconductor laser module and a helium-neon laser has been compared. Criteria are proposed for an objective numerical estimation of the quality of zero order Bessel light beams and trial calculations have been performed to obtain the quality parameters of Bessel light fields formed by the axicon from the radiation of the semiconductor laser module and helium-neon laser.
