Tm(3+)/Ho(3+) codoped tellurite fiber laser.
Continuous-wave and Q-switched lasing from a Tm(3+)/Ho(3+) codoped tellurite fiber is reported. An Yb(3+)/Er(3+)-doped silica fiber laser operating at 1.6 microm was used as an in-band pump source, exciting the Tm(3+) ions into the (3)F(4) level. Energy is then nonradiatively transferred to the upper laser level, the (5)I(7) state of Ho(3+). The laser transition is from the (5)I(7) level to the...
متن کاملRaman soliton generation in microstructured tellurite fiber pumped by hybrid Erbium/Thulium fiber laser system
We demonstrate a fibre laser source generating ultrashort pulses tunable in the range 2-2.5 μm. The source is based on a hybrid Er/Tm fiber laser system and microstructured suspended-core tellurite fiber where Raman soliton shifting occurs. Nonlinear soliton dynamics is studied and possibility of tuning beyond 3 μm is shown.
متن کاملMode-locked thulium-bismuth codoped fiber laser using graphene saturable absorber in ring cavity.
We demonstrate mode locking of a thulium-bismuth codoped fiber laser (TBFL) operating at 1901.6 nm, using a graphene-based saturable absorber (SA). In this work, a single layer graphene is mechanically exfoliated using the scotch tape method and directly transferred onto the surface of a fiber pigtail to fabricate the SA. The obtained Raman spectrum characteristic indicates that the graphene on...
متن کاملLa-codoped Bismuth-based Erbium-doped Fiber Ring laser with 80-nm Tuning Range
A wideband tunable fiber ring lasers using 253.3-cm long La-codoped bismuth-based erbium doped fiber and a narrowband tunable MEMS filter are reported. The fiber ring laser is capable of tuning over 80 nm continuously from 1545 to 1625 nm with an average output power of -3 dBm and extinction ratio of 60 dB.
متن کاملHost dependent frequency upconversion of Yb3+/Tm3+-codoped oxyfluoride tellurite glasses
The upconversion luminescence properties of Yb3+/Tm3+-codoped oxyfluoride tellurite glasses under 980 nm excitation are investigated experimentally. The intense blue and relatively weak red emissions centered at 475 and 649 nm corresponding to the transitions G4 → H6 and 1
