摘要
首次实验观察到在1064nm激光泵浦下掺Er^(3+)石英光纤中的共振增强受激四光子混频现象和光学自由感应衰减过程.在频域和时域上实验证明了Er^(3+)的~4I_(11/2)激发态能级对受激四光子混频产生的反斯托克斯谱线的增强效应.
Resonance enhanced stimulated four-photon mixing and optical free induction decay have been first demonstrated in Er3+ doped silica fibers under the excitation of a 1064 nm laser. The enhancement of anti-Stokes of stimulated four-photon mixing by the excited state 4I11/2 of Er3+ has been confirmed in frequency- and time-domain.
