Abstract:
High-concentration Er:YAG single-crystal fibers have been grown using the laser-heated pedestal growth technique. Instability in the melt and concomitant opacity of fibers were observed at source concentrations higher than 15 mol.%. Spectroscopic examination shows that broadening of the linewidth of the ⁴I(13/2) → ⁴I(15/2) transition is strongly dependent on Er³⁺ concentration.
