DEVICE AND METHOD TO STABILIZE BEAM SHAPE AND SYMMETRY FOR HIGH ENERGY PULSED LASER APPLICATIONS

摘要

mixer to increase the beam intensity symmetry along an axis of the beam is selected initiation (where the beam extends from the first edge to the second edge along said ) , the beam mixer may comprise a plurality of mirrors that make up the space around the reverse path . With respect to the beam mixer , reverse path has a start and end point , and at the beginning of the first beam path from the end point of a portion of the edge vicinity of the beam path characterized in that the conversion to the second beam edge . In such form, the beam mixer may further comprise an optical member for splitting the beam into a first beam portion and a second beam portion , the optical member is placed in a reverse of the first beam path to the inverting path , the first beam after the part is moved along a reversing path , by recombining the first and second portions on a common beam path, the beam mixing .
