The wavelength-tunable fiber laser employing volume Bragg gratings and diffraction gratings was tuned from 1055 to 1112 nm with a linewidth of ~0.3 nm (FWHM), which was in good agreement with the calculated gain spectra. Optimization of tandem-pumped Yb fiber lasers and the prospect for further...
When wavelength selection was achieved using volume Bragg gratings in an external feedback cavity, the tandem-pumped Yb fiber laser produced maximum output powers of 7.0, 6.8, and 6.4 W at 1070 nm, corresponding to slope efficiencies of 88.2, 87.8, and 89.5%, for pump wavelengths of 1020, ...
The SESAM shows a uniform low-intensity reflectivity and a modulation depth up to 12% for the wavelength from 1000 to 1100 nm. A linear cavity all-normal dispersion Yb-doped fiber laser has proved its mode locking performance for the wavelength of both 1030 nm and 1064 nm....

fiber, a wavelength of an output laser is selected in the polarization-preserving fiber grating with two reflection peaks by adjusting the polarizationcontroller, so as to implement a stable operation of double wavelengths at a normal temperature and output a laser with a good polarization degree. ...

Hence the gain spectrum can be designed artificially in an active-ion-doped SC-PBGF, desirable for long-wavelength Yb fiber laser operation. At first, 1178 nm amplification seeded with a non-polarized and linearly-polarized FRL was carried out with the core launched powers of 4 W and 2 W,...
An Yb-doped fiber (Nufern PM980-XP) with 6/125 μm core-cladding diameters and 30 cm length was used as a laser gain medium and pumped by 976 nm laser diode via a wavelength-division multiplexer. A loop mirror was used as one of the cavity mirrors, and it was based on 50/50 ...
We report a multi-wavelength mode-locked Er/Yb codoped fiber laser with square nano-second pulse output, which is constructed with a "figure-of-eight" cavity structure. A section of polarization-maintaining Er/Yb co-doped double clad fiber was used as the gain medium and pumped by a fiber...
