Measurement of infrared magic wavelength for an all-optical trapping of ${}^{40}$Ca${}^{+}$ ion clock

Yao Huang, Hua Guan, Chengbin Li +6

For the first time, we experimentally determine the infrared magic wavelength for the ${}^{40}$Ca${}^{+}$ $4s{}^2{S}_{1/2}\to 3d{}^2{D}_{5/2}$ electric quadrupole transit…
