Numerical investigation of 1662 nm holmium-doped fiber lasers enabled by a 751 nm fiber laser pump

Shihang Xu;Yuan Chen;Yani Lin;Xindie Chen;Kaiqi Xu;Wensong Li

IEEE Journal of Quantum Electronics
Year: 2025 | Early Access Article |
In this study, we present a novel fiber laser that employs self-pumping from internal laser transitions to induce inversion in other transitions. Using the 5F4 + 5S2→5I5 laser transition at 1354 nm to populate the 5I5 level, the cascade laser oscillation at 1662 nm (5I5→5I7) in Ho3+-doped ZrF4 (Ho3+: ZrF4) fiber was investigated. A practical design of the cascade laser, which is pumped by a 751 nm...Show More

Dual Wavelength Pumping Scheme for Directly Diode-Pumped 75X-nm Fiber Lasers

Wensong Li;Yulun Wu;Shihang Xu;Peng Wang;Yuan Chen;Dawid Piatkowski

Journal of Lightwave Technology
Year: 2023 | Volume: 41, Issue: 22 | Journal Article |
Cited by: Papers (1)
For decades, researchers have been interested in developing efficient rare-earth-doped laser sources using dual-wavelength pumping. However, dual-wavelength pumping of rare-earth-doped lasers and amplifiers are currently restricted to pump wavelengths longer than the visible. Extending the use of dual-wavelength pumping for directly diode-pumped rare-earth-doped lasers is of great importance for b...Show More

Pump Excited-State Absorption at 442 ± 1 nm for Efficient Visible Fluoride Fiber Lasers

Wensong Li;Zhibin He;Anxin Yu;Yulun Wu

Journal of Lightwave Technology
Year: 2023 | Volume: 41, Issue: 6 | Journal Article |
Cited by: Papers (5)
In the well-known excited-state absorption (ESA) process, population inversion of the laser transition can be achieved by a strong pump ESA involving a lower laser level. The exploitation of pump ESA has expanded from the visible to the near-infrared spectral range, based on various laser sources. Extending the operating wavelength of the pump ESA is greatly significant for the development of rare...Show More

All solid photonic bandgap fibers for high-power fiber lasers

Liang Dong;Turghun Matniyaz;Thomas W. Hawkins;Monica T. Kalichevsky-Dong;Saddam Gafsi;Wengsong Li

2020 Opto-Electronics and Communications Conference (OECC)
Year: 2020 | Conference Paper |
Fiber lasers have been increasingly playing a significant role in marking, cutting, welding, and other material processing industrial applications. Further power scaling of fiber lasers needs to overcome transverse mode instability and a range of nonlinear effects. Further improvements in effective mode area scaling and higher-order-mode suppression are essential. All-solid photonic bandgap fiber ...Show More

Green Wavelength-Tunable and High Power Ho3+-Doped Upconversion Fiber Lasers

Shuaihao Ji;Xiuji Lin;Meina Chen;Xiaofeng Rong;Huiying Xu;Wensong Li;Zhiping Cai

IEEE Photonics Technology Letters
Year: 2020 | Volume: 32, Issue: 6 | Journal Article |

Tunable coherent light source emitting at the visible region has long been recognized as a key asset, especially with a monolithic design involved, for the increasing number of emerging applications in the scientific research and industrial manufacturing. Here, an efficient 640 nm solid-state laser is used as a pump source, and the fiber end-facet mirrors construct a fiber laser resonator. We expe...Show More

Directly Blue Diode-Pumped Green Self-Q-Switched Ho3+-Doped Fluoride All-Fiber Laser at ∼550 nm

Wensong Li;Jiaji Wu;Zhiping Cai;Xiaofeng Guan;Huiying Xu

Journal of Lightwave Technology
Year: 2019 | Volume: 37, Issue: 22 | Journal Article |

We successfully demonstrate a blue diode-pumped green single-wavelength self-Q-switched Ho3+:ZrF4-BaF2-LaF3-AlF3-NaF (Ho:ZBLAN) all-fiber laser emitting at ~550 nm. Such a green laser, being a very simple device, consists of a 15-cm-long Ho:ZBLAN fiber and a pair of fiber input/output mirrors. The Ho:ZBLAN fiber not only acts as a gain medium but also works as a saturable absorber (SA). The modula...Show More

We report bidirectional red-light passively Q-switched all-fiber lasers based on a ring-cavity configuration using single-wall carbon nanotubes (SWNTs) as saturable absorber (SA). By manipulating the cavity design and intra-cavity polarization state, two sets of output pulses with different features could be achieved from the clockwise (C.W.) and counterclockwise (C.C.W.) directions, respectively....Show More
