英文摘要:
We report the demonstration of dual-wavelength laser output originating from excited Nd3+ ions and Yb3+ ions in Nd3+/Yb3+ co-doped phosphate glass fiber under 970-nm laser diode pumping. Using a free-space coupling method, laser bands at 1028 and 1053 nm were observed in a 35-cm-long fiber with the corresponding lasing thresholds of 4.3 and 31.5 W at room temperature. Emission and lasing spectra under different pump powers were tested by the optical spectrum analyzer. The 1053-nm laser threshold was found to be temperature sensitive. The mechanism of Yb3+ -> Nd3+ energy transfer under 970 nm pumping was explored. It was proposed that Yb3+ -> Nd3+ energy transfer process with the participation of phonon resulted in 1053-nm laser of Nd3+ ions in this co-doped fiber under 970 nm pumping.
