摘要
首次报道了实验研究连续1064nm激光泵浦的掺Er^(3+)石英光纤中频率上转换过程.测量了Er^(3+)/GeO_2/SiO_2和Er^(3+)/Al_2O_3/GeO_2/SiO_2两种光纤发射的可见荧光谱,并用Er^(3+)离子的双光子吸收和受激态吸收过程解释了频率上转换现象.
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.
