Absolute frequency measurement of the 5s5p ${}^1{P}_1$ - 5s5d ${}^1{D}_2$ transition in strontium

Ana Cipriš, Ivana Puljić, Damir Aumiler +2

We report on the absolute frequency determination of the 5s5p ${}^1{P}_1$ - 5s5d ${}^1{D}_2$ transition in atomic strontium, achieved through frequency comb-referenced laser-induced-fluore…
