摘要

Double resonance optical pumping spectroscopy has an outstanding advantage of high signal-to-noise ratio,thus having potential applications in precision measurement.With the counter propagated 780nm and 776 nm laser beams acting on a rubidium vapor cell,the high resolution spectrum of 5S1/2-5P3/2-5D5/2 ladder-type transition of 87 Rb atoms is obtained by monitoring the population of the 5S1/2 ground state.The dependence of the spectroscopy lineshape on the probe and coupling fields are comprehensively studied in theory and experiment.This research is helpful for measurement of fundamental physical constants by high resolution spectroscopy.
