Abstract

We demonstrated a pulsed ytterbium all-fiber laser passively Q-switched using excited-state absorption of thulium fiber and a mode-field-area mismatch. The absorption cross section of the excited state 3 F4 was measured and deter-minedtobethe key factor inducing pulsing, and it was much higher than that of the ground state 3 H6 over 0.95-1.15 μm. By successfully realizing the pulsed laser at 1030 nm, which is the most critical wavelength for Q-switching, we verified that the excite state 3 F4 of Tm3+ could be a full-range saturable-absorber Q-switch for a Yb fiber laser over 1.0-1.15μm.
