Diffuse Laser Cooling Based on the $6 P_{3/2}$ Excited State of Rubidium Atoms via 420 nm Blue Light

Jia Zhang, Xun Gao Zheng Xiao, Xiaolei Guan Ruihang Chen +2

To date, the laser cooling of rubidium atoms has inevitably relied on 780 nm cooling light corresponding to the first excited state $5 P_{3/2}$ . Surprisingly, we demonstrat…

Investigating the $4 D_{3/2} ∣3, \pm 2 ⟩$ -- $4 D_{5/2} ∣3, \pm 2 ⟩$ transition in Nb $^{4 +}$ for a THz atomic clock

Jyoti, A. Chakraborty, Zhiyang Wang +4

In this work, the $4 D_{3/2} ∣3, \pm 2 ⟩ \to 4 D_{5/2} ∣3, \pm 2 ⟩$ transition in the Nb $^{4 +}$ ion is identified as a promising candidate for a terahertz (THz) atomic cl…
