Abstract
We propose and theoretically analyze three-level cladding-pumped fiber
lasers in which the laser-active dopant is placed in a ring around a single-mode
core. A ring-doped laser can work efficiently at wavelengths with strong small-signal
absorption. This is otherwise difficult in a cladding-pumped fiber. Moreover,
ring doping makes the laser less sensitive to quenching of the laser-active
dopant and to excited-state absorption of the lasing field. In simulations
of a -doped fiber laser, ring doping increased the slope efficiency to
62%, up from 13% for a conventional core-doped fiber.
