Abstract
In the present invention, the methods and apparatus for making efficient laser beam coupling are disclosed. In particular, new structures for shaping and rearranging laser beams from diode laser array are disclosed. Along with the use of unique methods for coupling pumping laser beam into optical fiber or other media, high efficiency can be achieved. These aspects of the present invention will facilitate the realization of high-efficiency and high-power fiber lasers or other solid state lasers. The beam shaping structures can significantly improve the quality of the beams from diode laser array, and is easy to realize and less demanding in system alignment. Thus, a diode-pumped solid state laser of this invention may comprise a laser medium, a focusing means, a beam source comprising at least one laser diode array, a beam offsetting means, an image optics and a beam redirection means.
