Fabrication of 16 W all-normal-dispersion mode-locked Yb-doped rod-type fiber laser with large-mode area |
Schematic of the rod-fiber based ANDi laser (DM: dichroic mirror, LP: long pass mirror, HR: high reflective mirror, QWP (HWP): quarter (half) wave plate, BPF: birefringent plate filter, GLP: Glan laser polarizer, FR: Faraday rotator). |
