Empirical LiK excited state potentials: connecting short range and near dissociation expansions
Sofia Botsi, Anbang Yang, Mark M. Lam +4
We report on a high-resolution spectroscopic survey of molecules near the dissociation threshold and produce a fully…
Directional THz generation in hot Rb vapor excited to a Rydberg state
Mark Lam, Sambit B. Pal, Thibault Vogt +2
We optically excite Rb atoms in a heated vapor cell to a low-lying Rydberg state 10D and observe directional terahertz (THz) beams at 3.3 THz and 7.8 THz. These THz…
Singlet Pathway to the Ground State of Ultracold Polar Molecules
Anbang Yang, Sofia Botsi, Sunil Kumar +5
Starting from weakly bound Feshbach molecules, we demonstrate a two-photon pathway to the dipolar ground state of bi-alkali molecules that involves only singlet-to-singlet optical…
Collimated UV light generation by two-photon excitation to a Rydberg state in Rb vapor
Mark Lam, Sambit B. Pal, Thibault Vogt +3
We use two continuous-wave (CW) laser beams of 780 nm and 515 nm to optically drive Rb atoms in a heated vapor cell to a low-lying Rydberg state 10D. We observe a co…
Efficient microwave-to-optical conversion using Rydberg atoms
Thibault Vogt, Christian Gross, Jingshan Han +4
We demonstrate microwave-to-optical conversion using six-wave mixing in Rb atoms where the microwave field couples to two atomic Rydberg states, and propagates collinearly w…
Probing the dynamics of an optically trapped particle by phase sensitive back focal plane interferometry
Basudev Roy, Sambit Bikas Pal, Arijit Haldar +3
The dynamics of an optically trapped particle are often determined by measuring intensity shifts of the back-scattered light from the particle using position sensitive detectors. W…
Self assembly of microparticles in stable ring structures in an optical trap
Arijit Haldar, Sambit Bikas Pal, Basudev Roy +2
Micro-particle self assembly under the influence of optical forces produced by higher order optical beams or by projection of a hologram into the trapping volume is well known. In…
Measurement of probe displacement to the thermal resolution limit in photonic force microscopy using a miniature quadrant photodetector
Sambit Bikas Pal, Arijit Haldar, Basudev Roy +1
A photonic force microscope comprises of an optically trapped micro-probe and a position detection system to track the motion of the probe. Signal collection for motion detection i…
