Spectral properties and photon-gated spectral hole burning in SrBa (SO_4)_2: Sm^(2+)

报道了Sm^(2+)在SrBa(SO_4)_2混晶中的光谱性质和光子选通光谱烧孔效应。在这个材料中Sm^(2+)的~5D_o-~F_o歹。跃迁的不均匀增宽达1nm(766GHz)。利用Ar^+激光在514.5nm的输出和可调谐连续染料激光器在625.8nm附近的输出,在5K观测到~5D_1←→~7F_o跃迁的光子选通光谱烧孔效应。同时给出了Sm^(2+)在SrBa(SO_4)_2中的电子能级和有关的荧光和激发光谱。

Spectral properties and photon-gated spectral hole burning of Sm2+ in SrBa (SO4)2 mixed crystal are reported. The inhomogeneous broadening of 5D0-7F0 transition of Sm2+in this material is extended to lnm(766G-Hz). Using the output oi Ar+ laser at 514.5nm and the output of the CW dye laser at around 632.8um, photon-gated spectral hole burning at 7F0-6D1 transition at 5K was observed and the electron energy level and relevant fluorescence and excitation spectra of Sm2+ in SrBa(SO4)2 are given.
