Direct Measurement of the $5 s 5 p^{1} P_{1} \to 5 s 4 d^{1} D_{2}$ Decay Rate in Strontium

Naohiro Okamoto, Takatoshi Aoki, Yoshio Torii

We report the first direct experimental determination of the branching ratio of the $5 s 4 d^{1} D_{2} \to 5 s 5 p^{3} P_{2}$ transition and the decay rate of the $5s5p\,{}^1P_1 \to 5s4d\,…

Analyzing the optical pumping on the $5 s 4 d^{1} D_{2} - 5 s 8 p^{1} P_{1}$ transition in a magneto-optical trap of Sr atoms

Naohiro Okamoto, Takatoshi Aoki, Yoshio Torii

We explore the efficacy of optical pumping on the $5 s 4 d^{1} D_{2} - 5 s 8 p^{1} P_{1}$ ( $448 nm$ ) transition in a magneto-optical trap (MOT) of Sr atoms. The number of trapped…

Direct loading of a Sr magneto-optical trap from a thermal atomic beam

Naohiro Okamoto, Takumi Sato, Takatoshi Aoki +1

We demonstrate direct loading of a strontium (Sr) magneto-optical trap (MOT) from a thermal atomic beam in a single-chamber vacuum system. The MOT operates without a Zeeman slower,…

Limitation of single-repumping schemes for laser cooling of Sr atoms

Naohiro Okamoto, Takatoshi Aoki, Yoshio Torii

We explore the efficacy of two single-repumping schemes, $5 s 5 p^{3} P_{2} - 5 p^{2}^{3} P_{2}$ ( $481 nm$ ) and $5 s 5 p^{3} P_{2} - 5 s 5 d^{3} D_{2}$ ( $497 nm$ ), for a ma…
