Narrow-line imaging of single strontium atoms in shallow optical tweezers [PDF]
Phys. Rev. Research 4, 023245 (2022), 2022 Single strontium atoms held in optical tweezers have so far only been imaged using the broad $^{1\hspace{-0.3ex}}S_0$-$^{1\hspace{-0.3ex}}P_1$ transition. For Yb, use of the narrow (183 kHz-wide) $^{1\hspace{-0.3ex}}S_0$-$^{3\hspace{-0.3ex}}P_1$ transition for simultaneous imaging and cooling has been demonstrated in tweezers with a magic wavelength ...
