Self - starting all - polarization maintaining Yb - fiber laser with a polarization maintaining anomalous dispersion higher - order - mode fiber

A 100 W all-fiber linearly-polarized Yb-doped single-mode fiber laser at 1120 nm.

A 100 W-class all-fiber linearly-polarized single-mode fiber laser at 1120 nm with an optical efficiency of 50% was demonstrated. The laser consists of a 4.2 m long Yb-doped polarization maintaining fiber with a core diameter of 10 μm and a pair of FBGs written in matched passive fiber. Linearly polarized output with a polarization extinction ratio of 15 dB is achieved by a cavity that selects ...

High-power femtosecond Yb-doped single-polarization photonic crystal fiber laser

We report, to the first time to our knowledge, on a passively mode-locked single-polarization single-transverse-mode large-mode-area photonic crystal fiber laser operating in the dispersion compensation free regime. In the single-pulse regime, the laser generates 1.6 W of average power with 3.7 ps pulses at a repetition rate of 63 MHz, corresponding to a pulse energy of 25 nJ. Stable and self-s...

The Evolution of Dual-Wavelength Dissipative Soliton in Yb-Doped Fiber Lasers

Dual-wavelength dissipation soliton (DS) in the all-normal-dispersion ytterbium-doped fiber laser (YDFL) is reported. Using a phase-shift long period fiber grating (PS-LPFG) as an all-fiber format spectral filter in the laser cavity, self-starting dual-wavelength pulses are obtained by nonlinear polarization evolution (NPE). The mode-locking mechanism of the ANDi cavity with different central w...

Yb-Doped and Hybrid-Structured Solid Photonic Bandgap Fibers and Linearly-Polarized Fiber Lasers Oscillating above 1160 nm

We review our recent work on Yb-doped and hybridstructured solid photonic bandgap fibers (Yb-HS-SPBGFs) for linearlypolarized fiber lasers oscillating in the small gain wavelength range from 1160 nm to 1200 nm. The stack-and-draw or pit-in-jacket method is employed to fabricate two Yb-HS-SPBGFs. Both of the fiber shows optical filtering property for eliminating ASE in the large gain wavelength ...
