A method and device for generating a collimated laser beam which is circular in cross-section, non-astigmatic, diffraction-limited and has a gaussian energy distribution are disclosed. The device comprises a single mode optical waveguide having an input end and an output end, a laser diode optically coupled to the input end of the optical waveguide for producing at the output end thereof a laser beam which is circular in cross-section, non-astigmatic and diffraction-limited and has a gaussian energy distribution, and a collimating lens for collimating the laser beam. The collimating lens is disposed in spaced relationship to the output end of the optical waveguide such that the output end is positioned at the focal point of the collimating lens.
