Study on the Technique of Beam Coupling for High Power Diode Laser Stack

Abstract

High-power lasers based on GaAs bars meanwhile are well established as reliable and highly efficient laser sources. Continuous improvement of the material itself, mounting and cooling techniques during the last years have led to increased output power and high lifetimes. This paper summarized beam shaping technology of high-power lasers and evaluated these advantages and disadvantages. The beam coupling methods of the high power laser array were expatiated and a new beam coupling structure was present in the paper, also as the results and analysis of polarization coupled experiment.
