Reflection Spectroscopy and Transmission Spectroscopy by a Thin Vapor Medium

通过数值分析研究了超薄气体的透射与反射光谱特性与其厚度大小的对应关系。研究表明 ,透射光谱随薄膜厚度的增大而展宽 ,光谱呈现对称性。而在反射的情况下 ,这一对称性由薄膜厚度为 1

Optical properties of thin vapor layers are strongly affected by the influence of the boundaries. The symmetry properties of the optical coherence with respect to the detuning of the light frequency from resonance show up in specific symmetries of the spectra. In the case of reflection, this symmetry depends on whether a quarter wavelength fits an even or an odd number of times in the layer thickness. [WT5HZ]
