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

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.

Operation of an optical in-well-pumped vertical-external-cavity surface-emitting laser
, 2006 We report the operation of an optical in-well-pumped vertical-external-cavity surface-emitting laser. The laser delivers 1 W at 855 nm and is pumped with a cost-effective fiber-coupled laser diode emitting at 806 nm.
