Satellite-assisted laser magnetometry with mesospheric sodium
Tong Dang, Emmanuel Klinger, Felipe Pedreros Bustos +3
Magnetic field sensing provides crucial insights into various geophysical phenomena such as atmospheric currents, crustal magnetism, and oceanic circulation. In this paper, a metho…
Intensity Correlated Spiking Emission Due to Cooperative Effects in Alkali Vapors
Alexander M. Akulshin, Nafia Rahaman, F. Pedreros Bustos +3
Spiking behavior and a high degree of intensity correlation of frequency up- and down-converted directional radiation from population-inverted alkali vapors excited with a continuo…
A Precise Photometric Ratio via Laser Excitation of the Sodium Layer II: Two-photon Excitation Using Lasers Detuned from 589.16 nm and 819.71 nm Resonances
J. Albert, D. Budker, K. Chance +5
This article is the second in a pair of articles on the topic of the generation of a two-color artificial star (which we term a "laser photometric ratio star," or LPRS) of de-excit…
Polychromatic forward-directed sub-Doppler emission from sodium vapour
Alexander M. Akulshin, Felipe Pedreros Bustos, Nafia Rahaman +1
The mechanisms responsible for ultraviolet to mid-infrared light generation in sodium vapours two-photon excited with continuous-wave sub-100 mW power resonant laser radiation are…
Continuous-wave mirrorless lasing at 2.21 μm in sodium vapors
Alexander M. Akulshin, Felipe Pedreros Bustos, Dmitry Budker
We demonstrate backward-directed continuous-wave (cw) emission at 2.21 μm generated on the 4P3/2-4S1/2 population-inverted transition in Na vapors two-photon excited with resonant…
