Mode-locked Bi-doped fiber laser

Bi-doped fiber lasers

“…It is anticipated that obtained results could be significantly improved by construction of a Bi fiber laser with linear output polarization and a narrow linewidth. Two types of pulsed Bi-doped fiber lasers have been demonstrated recently -a mode-locked Bi-doped fiber laser [48,49] and a Q-switched Yb-Bi fiber laser [47].…”

Long-range soliton interactions through gain-absorption depletion and recovery

“…The relaxation of the saturated gain in these fibers is orders of magnitude faster than in fibers doped with rare earth elements. An additional factor is a saturated absorption that is also characterized by rather fast recovery [19][20][21]. In the cavities of such lasers, the formation of stationary soliton groups with interpulse distances decreasing from a leading to a trailing edge has been observed experimentally.…”

Bismuth fiber integrated laser mode-locked by carbon nanotubes

“…A strong peak is observed at ∼1170 nm, close to the desired operation wavelength, in correspondence to the first transition of (7,6) SWNTs [34]. Another band at ∼1028 nm is also seen, assigned to (6,5) SWNTs [34]. …”
