The fiber laser's excellent focus and efficiency, small size and light weight makes it highly promising not only for telecommunication, but also for industry and medical applications. In a double clad fiber laser, the inner cladding for guiding the pump light is provided around a core doped with active ion (e.g. YB3+, Nd3+, Er3+, etc.). The recent progress of fiber laser is reviewed at first in this paper. Different shapes of inner cladding are investigated to increase the pumping efficiency. Beam-shaping optics deliver high-power beams as the pumping source is discussed. Finally, a 4.9W cw double-clad fiber laser demonstration experiment in SIOM is described.
