CVD-grown MoSe2 with high modulation depth for ultrafast mode-locked erbium-doped fiber laser
Nanotechnology, 2018Two-dimensional materials have been widely used as optical modulator materials in mode-locked fiber lasers. In terms of the performance of the fiber laser, one with an ultrashort pulse and high stability has great commercial value.

Fiber and Integrated Optics, 1979
Optical fibers can exhibit wavelength conversion and other nonlinear optical effects at powers less than one watt. The reason has little to do with the glass in the fiber core, which is one of the least nonlinear of all materials, but rather with the tremendous interaction length possible in low-loss fibers.

Ultrafast thulium fiber laser system emitting more than 1 kW of average power.
Optics Letters, 2018In this Letter, we report on the generation of 1060 W average power from an ultrafast thulium-doped fiber chirped pulse amplification system. After compression, the pulse energy of 13.2 μJ with a pulse duration of 265 fs at an 80 MHz pulse repetition ...

Monolithic fiber laser oscillator with record high power
Laser Physics Letters, 2018With an increasing output power, the power scaling of monolithic fiber laser oscillators faces the severe limitations of stimulated Raman scattering (SRS) and the transverse mode instability (TMI) effect.

Fiber Raman lasers are broadly tunable optical frequency converters based on stimulated Raman scattering and Raman oscillation in low-loss glass fibers. Their practically and efficiency are based on the long interaction lengths possible in such fibers. Their relative simplicity and wide spectral region of operation make fiber Raman lasers attractive as

2022 Conference on Lasers and Electro-Optics Pacific Rim (CLEO-PR), 2022
The introduction of dual wavelength pumping nearly a decade ago has made the 3.5 µm transition in erbium doped fluoride glasses viable. This has enabled a host of new lasers with interesting properties to be developed.

Extruded Microstructured Fiber Lasers
IEEE Photonics Technology Letters, 2012We present the first fiber laser fabricated from an extruded microstructured preform. This laser is also, to the best of our knowledge, the first microstructured tellurite glass fiber laser. The threshold and efficiency of the 980-nm pumped, 1.5-μm erbium-doped tellurite laser were measured to be 1.5 mW and 13%, respectively.
