The gain and nonlinear medium was Cr 4+:Y 3Al 5O 12 double-clad crystal fiber grown using the codrawing laser-heated pedestal growth technique. The RCFL threshold was only 50 mW, and the slope efficiency reached 14.3% above a pump power of 350 mW. The result is in good agreement with theory, which indicates a near-100 quantum efficiency of resonant stimulated Raman scattering. © 2012 American Institute of Physics.Continuous waves; Crystal fiber; Double-clad; Intracavities; Laser heated pedestal growth; Nonlinear medium; Pump power; Raman crystals; Resonant Raman; Slope efficiencies; Fiber lasers; Crystal whiskersjournal article10.1063/1.47309492-s2.0-84863319958
