Abstract
We report the first absolute frequency measurements for the PD transition at 394 nm for all the stable strontium isotopes by utilizing repumping induced spectroscopy in a magneto-optical trap. Absolute transition frequency is measured to be 760524409251(25) kHz for Sr.With reference to Sr, the isotope shifts are measured to be 91052(35), 54600(33), and 51641(28) kHz for Sr, Sr, and Sr, respectively. We calculate the hyperfine constants A and B for the fermionic isotope Sr at kHz level. Furthermore, we perform King plot analysis by combining isotope shifts on the 689-nm transition to our data.
