Abstract
A method of direct diode pumping a fiber laser includes disposing a plurality of diode lasers in a wavelength beam combining cavity for generating a wavelength beam combining laser output, and optically coupling the wavelength beam combining laser output to the gain medium of a fiber laser. The wavelength beam combining cavity may comprise a fast axis wavelength beam combining cavity. Also, the plurality of diode lasers may comprise a multidimensional array of diode lasers arranged as diode laser bars disposed in a stack and spatially interleaved or optically aligned to form an optical stack. Each of the diode lasers may produce a distinct wavelength laser beam.
