The spectrum of degenerate four-wave mixing in Na vapor is shown to be purely dispersive for Rabi frequencies between the natural linewidth and the Doppler width. This result is qualitatively explained by the fact that absorption saturates much faster than dispersion.
钠蒸汽中简并四波混频的光谱在拉比频率介于自然线宽和多普勒宽度之间时被证明是纯色散的。这一结果可通过吸收比色散饱和快得多这一事实得到定性解释。
