1.6 GHz Frequency Scanning of a 482 nm Laser Stabilized using Electromagnetically Induced Transparency
Krishnapriya Subramonian Rajasree, Kristoffer Karlsson, Tridib Ray +1
We propose a method to continuously frequency shift a target laser that is frequency stabilized by a reference laser, which is several hundreds of nanometers detuned. We demonstrat…
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 transition rate in a…
Observation of the Rb to 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…
Generation of cold Rydberg atoms at submicron distances from an optical nanofiber
Krishnapriya Subramonian Rajasree, Tridib Ray, Kristoffer Karlsson +2
We report on a controllable, hybrid quantum system consisting of cold Rydberg atoms and an optical nanofiber interface. Using a two-photon ladder-type excitation in Rb, we d…
A simple, narrow, and robust atomic frequency reference at 993 nm exploiting the rubidium (Rb) to transition using one-color two-photon excitation
Thomas Nieddu, Tridib Ray, Krishnapriya S. Rajasree +2
We experimentally demonstrate a one-color two-photon transition from the ground state to the excited state in rubidium (Rb) vapor using a co…
