High-Order Mode Mode-Locked Fiber Laser Based on Few-Mode Saturable Absorber
IEEE Photonics Journal, 2021 We presented two kinds of high-order mode (HOM) mode-locked fiber lasers based on few-mode (FM) saturable absorbers for direct HOM oscillation. One is a ring fiber laser based on a carbon nanotube (CNT) saturable absorber (SA), in which the combination ...
