Abstract

For the first time to our knowledge, a radially polarized beam is generated in an Yb-doped multimode double-clad fiber laser by using an intracavity dual conical prism. Up to 6.2 mW of output power is obtained from a 2 m long gain fiber with 7.4\% slope efficiency. This research opens a new window to obtaining a radially polarized beam directly from an active fiber.
