Ht. Zhao et al., Measurement of the transition of barium 6s6p P-1(1)<- 6s6s S-1(0) using cavity ringdown spectroscopy, ACT PHY C E, 50(7), 2001, pp. 1274-1278
We report a set-up for cavity ringdown absorption spectroscopy, and we have
measured the line profile of the resonance 6s6p(1)P(1) <-- 6s6s S-1(0) of
barium atoms using cavity ringdown spectroscopy method. The absorption spec
troscopy line profile of Ba at different temperatures near 553.548nm is gai
ned. The experimental results indicate that the precision for the absorptio
n measurement has reached up to 6 x 10(-7).
