    Abstract: PURPOSE: An apparatus and a method for homogenizing laser beam by using a split-recombination method are provided to increase the homogeneity by compensating the movement of a center axis between the superposed beams. CONSTITUTION: An apparatus for homogenizing laser beam by using a split-recombination method includes a beam splitter(1), the first prism(2), the first and the second total reflection mirrors(4,5), the second prism(3), and a beam refractor(6). The beam splitter(1) is used for dividing the incident beam(7) into the first and the second beams(9,8). The first beam(9) penetrates the beam splitter(1) and the second beam(8) is reflected by the beam splitter(1). The first prism(2) is used for dividing the second beam(8) into the third and the fourth beams(10,11). The first and the second total reflection mirrors(4,5) are used for inverting the waveform of the third beam(10) and the waveform of the fourth beam(11). The second prism(3) is used for recombining the inverted beams(12,13). The beam refractor(6) is used for transmitting the recombined beam(14), reflecting the recombined beam(14) by means of the beam splitter(1), supposing the reflected beam on the first beam(9), and adjusting a center axis of the supposed beam(15) to the center axis of the first beam(9).

    Abstract: The present invention relates a method an apparatus capable of controlling an accurate wavelength of a wavelength conversion laser while continuously maintaining a single class mode without mode hopping of a class mode by rotating a prism instead of a wavelength conversion mirror by using a wedge prism. In the method, a wedge prism(4) is inserted into a single class mode wavelength conversion laser resonator and rotates to thereby control a wavelength of a single class mode wavelength conversion laser accurately.
