Abstract
An all-fiber ring resonator, constructed from a single strand of single-mode optical fiber and a directional coupler, is shown to have a low threshold for stimulated Brillouin laser action. The 10-m-perimeter fiber ring resonator has a low round-trip loss of under 3.5% and an inherent pump-power enhancement of approximately 30. Lasing threshold for the 4.0-μm-core fiber occurred with a pump power of 0.56 mW at λ = 6328 Å and 1.74 mW at λ = 5145 Å.
