Abstract We report the experimental results on controlling the oscillation wavelength by inducing force‐induced fiber gratings in Tm/Ho co‐doped fiber ring resonators. The fiber grating generates the resonance loss bands that are controlled with an electromagnet. The oscillation wavelength covers from 1879 nm to 1995 nm overall by shifting the passband that appears between the neighboring loss bands.
