1. A multiple beam laser system, comprising:

  • a laser capable of emitting a linearly polarized laser beam;

    at least one partially transmissive and partially reflective beam splitter capable of transmitting and reflecting the laser beam at a nearly linear polarization and which introduces no polarization change to the laser beam and which is capable of dividing the laser beam emitted by the laser into two laser beams;

    a half wave plate disposed in an optical path of a selected one of the laser beams, the half wave plate being capable of being rotated to alter the polarization direction the laser beam;

    a polarizer disposed in the optical path of the selected laser beam for adjusting the laser power of the selected laser beam at a selected polarization direction;

    an adjustable beam expander disposed in the optical path of the selected laser beam to adjust the size of the selected laser beam;

    a quarter-wave plate disposed in the selected beam after the beam splitter for introducing circular polarization into the selected laser beam; and

    a focusing lens for focusing the selected laser beam to a desired spot size.
