Glass-clad crystal fibers were grown using the codrawing laser-heated pedestal growth method. Both single-clad and double-clad structures were attempted. Using a 446-nm laser diode as the pump, 2.45 mW of collimated broadband emission was generated with a 3-dB bandwidth of 180 nm. As much as 7.7 mW of output power with a 3-dB bandwidth of 182 nm was generated using...
Using laser heated pedestal method to grow CaO or MgO side deposited Cr4+:YAG crystal fiber, Cr4+ concentration was raised by a factor of 110% after re-growth and annealing at 1350degC in Ca,Cr:YAG crystal fiber.
