As the increasing applications of the semiconductor lasers in the laser processing  the single 2-D stack optic-power density has not satisfied the actual requirements. It demands to couple several diode laser stack beams to one to improve the brightness  and it becomes the central issue to adopt the appropriate beam coupling technology which would offer high quality and high efficiency. In this paper  it mainly introduces the beam shaping and the technology of spatial coupling  polarization coupling  and wavelength coupling. The coupling key elements are presented and indicated. Finally  the development of the diode laser on beam coupling in our country fell behind through analyzing the statement of the world. Our lab is studying on polarization coupling and wavelength coupling. We gain some results by phase  which the polarization coupling efficiency can achieve 90% for two LD stacks with seven bars whose luminous wavelength is 975nm and980nm.By two 808nm diode laser coupling  the efficiency of 60% can be achieved after focusing to the beam size of 22mm2. 2008 SPIE.
