Simulation of Thermal Effects in Totally and Partially Pumped Solid-State Laser Rod with Side-Pumping Structure [PDF]
Engineering and Technology Journal, 2014 In this work, a steady-state heat transfer equation in a side-pumped Nd:YAG laser rod was solved numerically using finite element method (FEA). The resulting temperature and stress distributions were calculated under the condition of totally and ...

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.

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.

In-Well and Barrier Coupling Pump of Semiconductor Disk Laser
IEEE Photonics Journal, 2022 We report an in-well and barrier coupling pump scheme of semiconductor disk laser (SDL). An in-well-absorbed (940 nm) and a barrier-absorbed (808 nm) pump source were used to measure laser output characteristics. The output power of the coupling pump can

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

An optically driven pump for microfluidics
SPIE Proceedings, 2006 We demonstrate a method for generating flow within a microfluidic channel using an optically driven pump. The pump consists of two counter rotating birefringent vaterite particles trapped within a microfluidic channel and driven using optical tweezers. The transfer of spin angular momentum from a circularly polarised laser beam rotates the particles at

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 ...
