The present invention can improve the efficiency of high-power conventional lasers; and, therefore, it can be applied in advanced experiments such as second harmonic generation and amorphous silicon annealing and in the precision industry which requires a highly repetitive laser, since it can provide a laser beam having a uniform pattern and high directional properties.
