Saturated absorption spectroscopy of buffer-gas-cooled Barium monofluoride molecules
文献摘要：
We report an experimental investigation on the Doppler-free saturated absorption spectroscopy of buffer-gas-cooled Barium monofluoride(BaF)molecules in a 4 K cryogenic cell.The obtained spectra with a resolution of 19 MHz,much smaller than previously observed in absorption spec-troscopy,clearly resolve the hyperfine transitions.Moreover,we use these high-resolution spectra to fit the hyperfine splittings of excited A(v=0)state and find the hyperfine splitting of the laser-cooling-relevant A2∏1/2(v=0,J=1/2,+)state is about 18 MHz,much higher than the previous theoreti-cally predicted value.This provides important missing information for laser cooling of BaF molecules.
