A system for the reforming of a laser beam having a circular sector shaped beam cross section into a laser beam with a rectangular beam cross section, incorporates a mirror whose surface is shaped as the circular sector of a reflective parabolic rotational body. With only one mirror, and with only minor image aberrations, the circular sector shaped laser beam can be reformed into a rectangular laser beam.

Laser beam reforming system

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&deg;. 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.
