摘要：
We demonstrate the direct frequency comb spectroscopy of Rb 5S -> 5D two-photon transitions directly excited by an optical frequency comb (OFC) in 1.5 mu m fiber communication bands. A chain of comb spectral manipulation and quantum coherence control is implemented to enhance the efficiency of second harmonic OFC generation and eliminate the Doppler-broadening background. The direct frequency comb spectroscopy with clearly resolved transition lines is obtained. Our scheme provides a potential approach to realize the OFC at similar to 1.5 mu m with high stability and accuracy. (C) 2013 Optical Society of America
