  • 通过在锶蒸气和氦混合气体中的高重复率脉冲放电,同时获得了锶原子4条谱线的激光振荡,它们对应于复三能级4d·3D3,2,1与5p·3P02,1,0之间的多谱线跃迁,其波长分别为292μm,301μm,269μm和260μm.除了301μm激光外,均为首次报道.激光平均功率合计约10mW,相互之间的强度比为5∶4∶4∶1.在分析了相关能级特征和实验现象的基础上,对其作用机理进行了初步的探讨,建议将其分
    A set of laser oscillations of four strontium atom spectral lines simultaneity have been obtained, through high-repetition-frequency pulsed discharge in mixed gases of strontium vapor and helium buffer gas. The corresponding wavelengths with the transitions from compound three-energy levels 4d·3D3,2,1 to 5p·3P02,1,0 are 2.92μm, 3.01μm, 2.69μm and 2.60μm respectively,their ratios of intensities are 5∶4∶4∶1 and the total average laser power is 10mW.As far as we know,the laser spectral lines have never been reported except 3.01μm.On the basis of analyzing characteristics of corresponding energy levels and experimental phenomena,the action mechanism is discussed primarily.We suggest the classification of the spectral lines to be named as M-M transition laser.
