项目摘要
Analytical detection sensitivity of the resonant magneto-optic effect in the Voigt configuration (transverse magnetic field) was investigated by using a narrow-band tunable dye laser as a light source and sodium atoms in a flame as a sample. The elliptically polarized laser beam was tuned to the sodium <D_2> line. The signal to noise ratio was optimized by adjusting the ellipticity of incident light and the orientation of the polarization analyzer. The observed profiles of the Voigt signal agreed with the theoretical prediction. The detection sensitivity of the Voigt effect was enhanced by a factor of 2 x <10^2> when compared with the atomic absorption in the same experimental arrangement. The absolute values of the atomic number density obtained from the Voigt effect and the absorption agreed within the experimental accuracy.
以窄带可调谐染料激光器为光源,以火焰中的钠原子为样品,研究了福伊特构型(横向磁场)中共振磁光效应的分析检测灵敏度。将椭圆偏振激光束调谐至钠<D_2>线。通过调整入射光的椭圆率和偏振分析器的方向来优化信噪比。观察到的 Voigt 信号轮廓与理论预测一致。与相同实验布置中的原子吸收相比,Voigt 效应的检测灵敏度提高了 2 x <10^2> 倍。由福伊特效应和吸收获得的原子序数密度的绝对值在实验精度内一致。
