Whether the transitions between 6s5d 3D and 5d6p 3F can be used for laser cooling of barium heavily depends upon the transition probabilities of 5d6p 3F-5d23F. Taking the transition 6s5d 3D32-5d6p 3F4 as a scale, the leakage rate of 5d6p 3F4-5d23F was used to evaluate the transition probabilities. 706 nm laser pulses with different durations were applied to a barium atomic beam for 6s5d3D3-5d 2 3F4 optical pumping, and the remaining percentages in 6s5d 3D3 were measured. After exponential fitting, the transition probability of 5d6p 3F4-5d2 3F3,4 was determined to be 2.1(4)×104 s-1, which is in agreement with theoretical calculations using the scaled Thomas–Fermi–Dirac method.
