Abstract
We report, for the first time to our knowledge, fundamental-mode operation in polarization-maintaining ytterbium-doped fiber with an effective area of and birefringence of . The measured critical bending radius, , defined as the radius at which the loss is equal to for of fiber, is . Lasing with slope efficiency exceeding 60% and of 1.2 has also been demonstrated.
