Abstract

We propose a three-layered W-type structure for laser fiber to facilitate the three-level radiative transition near 940 nm region of Nd ion, while suppressing the competing four-level transition near 1060 nm by introducing a novel highly wavelength selective loss mechanism. In order to achieve a net gain around 940 nm, requirements in fiber waveguide parameters for the LP ₀₁ mode cut-off and bending loss were theoretically investigated. The waveguide designs were experimentally confirmed generating stable CW single mode output power of 705 mW.
