Abstract Scope Single crystal fiber composed of rare earth doped YAG offers the potential for high power scaling of fiber lasers due to lower intrinsic stimulated Brillouin cross-sections and higher thermal conductivity. The use of rare earth doped YAG fibers also mitigates issues of photodarkening, multiphonon edge absorption, and OH-quenching observed in Ho doped silica fiber lasers operating at eye safe wavelengths. A model based on Yb and Ho single frequency fiber laser showed that YAG crystal fiber could carry as much as 10 times higher power than silica fiber. Rare earth doped single crystal YAG and sesquioxide fibers of various diameter and length have been drawn using a state-of-the-art Laser Heated Pedestal Growth system. We have developed claddings on these fibers using various crystal growth and deposition methods. We report on the various fabrication methods, morphology, and optical characterization of these single and double clad all-crystal fibers.
