Spin selection rule for {\it S} level transitions in atomic rubidium under paraxial and nonparaxial two-photon excitation

Krishnapriya Subramonian Rajasree, Ratnesh Kumar Gupta, Vandna Gokhroo +5

We report on an experimental test of the spin selection rule for two-photon transitions in atoms. In particular, we demonstrate that the $5 S_{1/2} \to 6 S_{1/2}$ transition rate in a…

Observation of the $^{87}$ Rb $5 S_{1/2}$ to $4 D_{3/2}$ electric quadrupole transition at 516.6 nm mediated via an optical nanofibre

Tridib Ray, Ratnesh K. Gupta, Vandna Gokhroo +4

Light guided by an optical nanofibre can have a very steep evanescent field gradient extending from the fibre surface. This can be exploited to drive electric quadrupole transition…
