Analysis of W-type waveguide for Nd-doped fiber laser operating near 940nm
Analysis of W-type waveguide for Nd-doped fiber laser operating near 940nm
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 LP01 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.

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 LP01 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.
