Abstract
A laser beam generating assembly for materials processing includes a resonator to generate a linearly polarized laser beam, and a beam forming assembly which includes mirrors to orient the polarization plane of the laser beam in a prescribed orientation relative to the vertical and a delay plate which has its reflective surface oriented so that the polarization plane of the beam impinges thereon is at an angle of 45°. The delay plate serves to produce a polarized laser beam with a rotating polarization vector, and in particular an elliptical or circular polarization of the laser beam.
