Abstract

A light beam reshaper by refraction aiming at two-dimension laminated light source is characterized in that the light beam reshaper comprises a first parallel flat mirror pile which is stacked by a plurality of flat mirrors and a second parallel flat mirror pile which is also stacked by a plurality of flat mirrors; wherein, the first parallel flat mirror pile and the second parallel flat mirror pile are arranged in sequence along the transmission direction of light beam. The light beam reshaper by refraction aiming at two-dimension laminated light source of the invention has the advantage that after the outgoing two-dimension light beam matrix getting through the reshaper, the shining dead zone is eliminated and becomes even-distributed beam with better focusing performance.

Description

technical field [0001] The invention relates to a refraction beam shaper for a two-dimensional laminated light source, which eliminates the dead zone of the beam of the two-dimensional laminated device, improves the quality of the output beam, and improves the brightness of the output light and the performance of coupling and focusing. Background technique [0002] Since the 1980s, with the advancement of semiconductor material growth technology, laser packaging and refrigeration technology, high-power semiconductor lasers with high power, long life and high packaging density have gradually matured. In recent years, stacked semiconductor lasers with the advantages of high output power, small size, and long life have developed rapidly. They are used in many fields such as industry, scientific research, and medicine, such as industrial laser processing, welding, pumping solid-state lasers, and laser surgery It has been widely used in many aspects. However, semiconductor laser...
