Frequency stabilization of rare-earth-doped fiber lasers by use of 3 x 3 nonplanar fused-fiber couplers.
We present a numerical analysis that indicates that a 3 x 3 nonplanar fused-fiber coupler can be used to inhibit longitudinal mode hops in a narrow linewidth unidirectional ring fiber laser. We also give preliminary experimental data that support our numerical analysis.
