Influence of Er^(3+) and Yb^(3+)/Er^(3+) doping on SHG in silica fibers

实验研究了掺Er^(3+)和Yb^(3+)/Er^(3+)石英光纤中的倍频过程.测量了不同Er^(3+)和Yb^(3+)/Er^(3+)掺杂量的光纤倍频转换效率和光纤倍频预处理前后Er^(3+)发射可见荧光的强度,探讨了Er^(3+)和Yb^(3+)掺杂对光纤中倍频过程的影响.

Second harmonic generation in Er3+ and Yb3+/Er3+ doped silica fibers has been demonstrated. The maximum peak power conversion efficiencies of fibers with various Er3+ and Yb3+/Er3+ doping have been measured. The visible fluorescence spectra emitted from Er3+ ons have also been recorded before and after the doped fibers were prepared to generate efficient SHG. And the influence of Er3+ and Yb3+/ Er3+ doping on SHG in silica fibers were discussed.
