Lamb-dip saturated-absorption cavity ring-down rovibrational molecular spectroscopy in the near-infrared
文献摘要：
The high-detection-sensitivity saturated-absorption cavity ring-down(SCAR)technique is extended to Lamb-dip spectroscopy of rovibrational molecular transitions in the near-infrared region.Frequency-comb-referenced sub-Doppler saturation measurements,performed on the acetylene(v1+υ3+υ4 ← υ4)R(14)e line at 6562 cm1,are analyzed by a SCAR global line profile fitting routine,based on a specially developed theoretical model.Compared to a conventional cavity ring-down evaluation,our approach yields dip profiles with a line-width freed from saturation broadening effects,reduced by 40％,and a signal-to-noise ratio increased by 90％.Ultimately,an overall(statistical and systematic)fractional uncertainty as low as 7×10-12 is achieved for the absolute line-center frequency.At the same time,our method is also able to accurately infer the linear(non-saturated)behavior of the gas absorption,providing Lamb-dip-based line strength measurements with a relative uncertainty of 0.5％.
