| Abstract: | Frequeney up-conversion in Er3+ doped silica fibers pumped by a CW 1064 nm laser has been first demonstrated. The visible fluorescence spectra of Er3+/GeO2/SiO2 and Er3+/Al2O3/GeO2/SiO2 optical fibers were measured. Two-photon absorption and excited-state-absorption of Er3+ ions are proposed to account for the experimental observation. |
