ABSTRACT:
A laser beam composite apparatus which combines more than three beams including a first beam having a first wavelength, a second beam having a second wavelength and polarized in a predetermined direction and a third beam having a second wavelength and polarized in a direction perpendicular to said polarized direction of said second beam. The laser beam composite apparatus combines the first beam and the second beam based on difference of wavelengths thereof and further combines the third beam based on difference of polarized directions thereof.
