摘要：

Water lines in the infrared are convenient frequency references. We present absolute positions of several H-2 O-16 ro-vibrational transitions around 790 nm using comb-locked cavity ring-down saturation spectroscopy. Lamb dips of 6 water lines with saturation power in the range of 70-130 kW/cm(2) were observed and the line positions were determined with an accuracy of 25 kHz, corresponding to a fractional uncertainty of 6.6 x 10(-1)1. The present work demonstrates the capability to considerably improve the accuracy of the water line positions in the infrared. (C) 2017 Elsevier Ltd. All rights reserved.
