Spatially truncated optical pumping cooling
New Journal of Physics, 2019 We present both the theoretical description and experimental implementation of a novel cooling technique for ultracold atoms trapped in a confining potential. We call the technique ‘spatially truncated optical pumping cooling.’ By using the fact that the

Reduction of the nonlinear phase shift induced by stimulated Brillouin scattering for bi-directional pumping configuration system using particle swarm optimization algorithm [PDF]
Journal of the European Optical Society-Rapid Publications, 2013 We present a theoretical analysis of an additional nonlinear phase shift of backward Stokes wave based on stimulated Brillouin scattering in the system with a bi-directional pumping scheme.

Nanomaterials, 2021 The effect of optical pumping and magnetic field on properties of the electronic phase separation regions, which are the multiferroic semiconductor heterostructures in the form of superlattices, have been studied in Eu0.8Ce0.2Mn2O5.

Optical Pumping and Vibrational Cooling of Molecules [PDF]
Science, 2008 The methods producing cold molecules from cold atoms tend to leave molecular ensembles with substantial residual internal energy. For instance, cesium molecules initially formed via photoassociation of cold cesium atoms are in several vibrational levels ν of the electronic ground state.

Nature Communications, 2021 Optical pulses can be useful to create and control molecules in higher quantum states. Here the authors use optical pumping to create rotationally excited states of SiO+ molecular ion into super rotor ensemble.

Crystals, 2023 We propose the use of an n-doped periodic AlN/GaN quantum cascade structure for the optical up-conversion of multiple near-infrared (near-IR) photons into deep-ultraviolet (deep-UV) radiation.

OPTOGALVANIC DETECTION OF OPTICAL PUMPING
Le Journal de Physique Colloques, 1982 We have used an optogalvanic method to detect observables induced by optical pumping in metastable states of neon. As with optical methods signals are obtained due to electronic and nuclear orientation or alignment. Different mechanisms are discussed from which optogalvanic signals related to non-scalar observables may originate. Profiles obtained from

Optical Pumping into Many-Body Entanglement [PDF]
Physical Review Letters, 2011 We propose a scheme of optical pumping by which a system of atoms coupled to harmonic oscillators is driven to an entangled steady state through the atomic spontaneous emission. It is shown that the optical pumping can be tailored so that the many-body atomic state asymptotically reaches an arbitrary stabilizer state regardless of the initial state ...

20 kW Monolithic Fiber Amplifier With Directly Dual-Wavelength Laser Diodes Counter Pumping
IEEE Photonics JournalIn this study, we demonstrate a high-power ytterbium-doped fiber laser (YDFL) based on laser diodes (LDs) directly pumping scheme. Tandem pumping and LD direct pumping are two common schemes for generating high-brightness laser output in YDFL.
