    • The invention relates to the method and device for generating the uniformalized laser beam, wherein passing through a triplet aplanatic convex lens, the focal point size is minimized, after the condensed laser beam being incident upon the optical fiber and passing through the bent optical fiber in circle form in first and second place (and third plane) each vertically arranged, is uniformed by accelerated screw increments and diffused reflections, the laser energy condensed in the center portion is diffused uniformly all over the section area, and also one base plate formed on which one bending guide for winding and suspending the optical fiber passing through each circular and local bending, and one local bending adjusting portion for shaping the said fiber wound around the local bending portion of said bending guide into locally bent form are fixed each other of one bending portion, by arranging and fixing said two bending portions vertically each other, the optical fiber is put in order along the bending guide surface for two bending portions.
