Abstract: A large number of passes of pump light through an active mirror in a solid state disk laser is realized using a pair of coupled imaging systems, where the optical axes of imaging systems are not coincident. Two imaging systems are optically coupled, so that an image of the first imaging system is an object of the second imaging system, and vice versa. An active mirror is disposed at the object or image plane, or at the focal plane of any one of the coupled imaging systems, where the position of the reflected pump beam during the multi-reflection between the first and second imaging systems is substantially unchanged.

Abstract: In the present invention, methods and apparatus for making efficient cladding pumping fiber lasers is disclosed. In particular, new fiber cladding geometry and new method of coupling pumping laser into an optical fiber are disclosed. Both aspects of the present invention will facilitate the realization of high-efficiency and high-power fiber lasers. In the present invention, cladding boundary geometry structures that can prevent the formation of local modes are disclosed. Besides the cladding geometry, methods for efficient coupling of diode lasers into a laser fiber for high power injection are also disclosed. Essentially, the new methods make it possible to transmit diode laser beams for a long distance with substantially the same brightness. In other words, with the methods and apparatus disclosed, a laser beam from a laser diode array with collimating structures can be transmitted for a long distance while the beam spot dimension including beam divergence can be kept substantially unchanged even if the beam from said array is not substantially collimated. With the method taught in the present invention, laser diode array modules can be formed with laser diode arrays (LDA) with collimating structures and relay systems. Because of the brightness conservation nature of the modules, when a plurality of such modules (such as 3, 9 or more than 200 pieces) are combined, the beams from the arrays can be efficiently coupled into an optical fiber. Thus the pumping laser coupling method can be used for the construction of high-efficiency and high-power fiber lasers. Thus, the fiber lasers of this invention may comprise of a fiber laser core doped with active species, a symmetry-broken inner cladding or a multiple-imaging inner cladding surrounding said core, a plurality of brightness substantially-conserved laser diode array module for coupling the beam from said laser diode array module into said inner cladding.

Abstract: A double cladding fiber includes an inner core doped with active species, an inner cladding disposed adjacent said inner core for receiving pumping energy, minimizing local modes in said inner cladding, and transferring said pumping energy to the core. An outer cladding is disposed adjacent the inner cladding. The cross section of said inner cladding has a polygon-like shape with its boundary being a plurality of well-defined arcs, each of the arcs having substantially different arc center for delivering energy with maximum efficiency to the inner core meeting the limitation of: (1nullL/r1)(1nullL/r2) 1; where r1 and r2 is the arc radius of the inner cladding surfaces that are opposite to each other (mirror pair), with the radius of a concave mirror being positive and that of a convex mirror being negative, L is the distance between two mirrors.
