Single polarisation operation of a Nd³⁺-doped single-mode fiber laser

Abstract

As a laser source, single-polarization fiber lasers are of considerable interest for many potential sensor applications. The fiber lasers reported to date have had essentially unpolarized outputs due to the difficulty of including intracavity polarization control components such as Brewster windows in the compact cavity of the fiber laser. Using a recently developed technique, we incorporated a low-loss high-extinction-ratio single-mode fiber polarizer into the cavity of a Nd³⁺-doped fiber laser. This technique exploits the interaction of the evanescent field of the lasing mode with a short length of metal embedded in the cladding of the fiber.
