ABSTRACT:
A laser apparatus comprises a plurality of laser beam sources for radiating out a plurality of laser beams such that the laser beams may intersect one another on a predetermined virtual plane, through which the laser beams pass. A Fourier transform lens array optical system, which divides the laser beams having impinged upon the virtual plane into small regions and carries out Fourier transform of the small regions, is located in the vicinity of the virtual plane. A laser resonator mirror optical system is constituted of a first laser resonator mirror, which is located at a position that receives the laser beams having been radiated out of the Fourier transform lens array optical system, and a second laser resonator mirror, which is located at a position rearward from the laser beam sources. The laser apparatus coherently combines the later beams with one another without reducing the radiant energy combining efficiency and thereby radiates out a combined laser beam having a high output power.
