Nanosecond Hybrid Q-Switched Er-Doped Fiber Laser With WS2 Saturable Absorber
IEEE Photonics Journal, 2016 We demonstrate a stable hybrid Q-switched Er-doped fiber (EDF) laser with WS2 as the saturable absorber (SA). The SA device is obtained by depositing WS2 on a tapered fiber using the pulsed laser deposition method.
