Abstract :
In this work, we present what we believe is the first QCW all-fiber laser emitting near 3 μm with a record high efficiency of 36.6% with respect to the absorbed pump power. Here, the 4.4 m-long Er3+-doped double-clad fluoride glass fiber was fusion spliced to a FBG of 96.8% reflectivity written in an undoped, mode-matched fiber.
