Abstract Scope Crystal fibers have higher thermal conductivity and higher stimulated Brillouin scattering thresholds compared to the traditional silica glass fiber and can be doped with higher rare earth concentrations. These properties are advantageous to realize high power fiber lasers. Calculations show one would expect more than 17 kW of single frequency output power from a single mode fiber laser based on a Yb:YAG single crystal fiber, as compared to ~1 kW for glass fibers. However, it has been traditionally difficult to fabricate high quality core/clad crystalline fibers primarily due to the unavailability of high quality crystal fiber and lack of proper cladding materials and cladding application methods. In this paper, we present our recent progress on developing cladded single crystal fibers. Results on the growth of various single crystal fibers, the selection and application of cladding materials on the crystal fibers, optical and physical properties, and preliminary lasing results are presented.
