Abstract
Method and apparatus are disclosed for beam dividing and shaping, in which the beams from laser diode array are divided in a plurality of sections along the slow axis and the sections of beams are then recombined along their fast axis so that the Lagrange invariant of the resulting beam increased approximately by n-fold in fast axis and reduced approximately by n-fold in slow axis. With the inclusion of above apparatus in diode laser modules, the main objectives of constructing high-efficiency solid state lasers can be achieved. Thus, a high-efficiency diode-pumped solid state laser apparatus can be made, comprising a laser fiber, at least one laser diode array module, an imaging optical system, wherein said imaging optical system is disposed between said module and the aperture of said fiber and focuses the beam from said module onto the aperture of said laser fiber, and wherein said laser diode array module comprises at least one laser diode array, a collimating structure, a beam dividing/rearranging device and an optical relay system.
