Abstract We present mechanically tunable Tm/Ho-codoped fiber lasers based on multimode interference in single mode-multimode-single-mode structures. The intermediate multimode fiber (MMF) is separated into two segments with a liquid core in between. The mode field diameter of the single-mode fiber is designed to 13 μm for the MMF having a core diameter of 105 μm. The tunable range is attained to 64 nm by extending the effective length of the MMF.
