首次利用内腔双锥棱镜在掺Yb多模双包层光纤激光器中产生径向偏振光束。从2m长的增益光纤中获得了高达6.2 mW的输出功率，斜率效率为7.4%。这项研究为直接从有源光纤获得径向偏振光束打开了一扇新的窗口。
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.
