-enhanced gray-molasses loading and EIT cooling of neutral atoms in nanophotonic traps
Lucas Pache, Antoine Glicenstein, Philipp Schneeweiss +3
Nanophotonic traps for cold atoms typically have trap volumes that are orders of magnitude smaller than, e.g., free-space optical tweezers. This makes efficient loading of these tr…
High-optical-depth, sub-Doppler-width absorption lines at telecom wavelengths in hot, optically driven rubidium vapor
Inna Kviatkovsky, Lucas Pache, Viola-Antonella Zeilberger +4
Doppler broadening presents a major limitation for high-resolution spectroscopy and nonlinear optics in room-temperature atomic vapors. Here, we demonstrate the suppression of Dopp…
Magic-wavelength nanofiber-based two-color dipole trap with sub- spacing
Lucas Pache, Martin Cordier, Hector Letellier +4
We report on the realization and characterization of a novel magic-wavelength nanofiber-based two-color optical dipole trap for cesium that allows us to generate two diametral peri…
State-Insensitive Trapping of Alkaline-Earth Atoms in a Nanofiber-Based Optical Dipole Trap
K. Ton, G. Kestler, D. Filin +7
Neutral atoms trapped in the evanescent optical potentials of nanotapered optical fibers are a promising platform for developing quantum technologies and exploring fundamental scie…
Observation of oscillatory Raman gain associated with two-photon Rabi oscillations of nanofiber-coupled atoms
Christian Liedl, Sebastian Pucher, Philipp Schneeweiss +2
Quantum emitters with a -type level structure enable numerous protocols and applications in quantum science and technology. Understanding and controlling their dynamics is, ther…
Precise Lifetime Measurement of the Cesium State
S. Pucher, P. Schneeweiss, A. Rauschenbeutel +1
We measure the lifetime of the cesium state using a time-resolved single-photon-counting method. We excite atoms in a hot vapor cell via an electric quadrupole transit…
