Single-photon cesium Rydberg excitation spectroscopy using 318.6-nm UV laser and room-temperature vapor cell
TL;DR: In this article, a single-photon Rydberg excitation spectroscopy of cesium atoms in a room-temperature vapor cell was demonstrated using a 318.6 nm ultraviolet (UV) laser.

Quantum-enhanced rubidium atomic magnetometer based on Faraday rotation via 795 nm stokes operator squeezed light
TL;DR: In this article, the PSS of Stokes operator S2 of 795-nm light has been prepared by coherently combining the polarization coherent state (PCS) of a linearly p-polarized bright 795nm light beam and the linearly s polarized squeezed vacuum state (SVS) generated by a 397.5-nm ultraviolet laser pumped sub-threshold optical parametric oscillator (OPO) inside the OPO cavity.

Cavity-enhanced frequency doubling from 795nm to 397.5nm ultra-violet coherent radiation with PPKTP crystals in the low pump power regime.
TL;DR: The constructed ultra-violet coherent radiation has good power stability and beam quality, and the system has huge potential in quantum optics and cold atom physics.

Measurement of magic-wavelength optical dipole trap by using the laser-induced fluorescence spectra of trapped single cesium atoms
TL;DR: Based on the multi-level model, light shifts for Zeeman states of hyperfine levels of cesium (Cs) 6S1/2 ground state and 6P3/2 excited state are calculated and influence of the trap depth and the bias magnetic field on the measurement results are discussed.

TL;DR: In this paper, a two-way single-photon-level frequency conversion between 852 nm and 1560 nm has been implemented with the same periodically-poled magnesium-oxide-doped lithium niobate (PPMgO:LN) bulk crystals for connecting cesium D2 line (852 nm) to telecom C-band.
