Quantum interference and light polarization effects in unresolvable atomic lines: application to a precise measurement of the 6,7 Li D2 lines
Roger C. Brown, Saijun Wu, J. V. Porto +5
We characterize the effect of quantum interference on the line shapes and measured line positions in atomic spectra. These effects, which occur when the excited state splittings ar…
Electron Temperature Evolution in Expanding Ultracold Neutral Plasmas
P. Gupta, S. Laha, C. E. Simien +4
We have used the free expansion of ultracold neutral plasmas as a time-resolved probe of electron temperature. A combination of experimental measurements of the ion expansion veloc…
Experimental Realization of an Exact Solution to the Vlasov Equations for an Expanding Plasma
S. Laha, P. Gupta, C. E. Simien +4
We study the expansion of ultracold neutral plasmas in the regime in which inelastic collisions are negligible. The plasma expands due to the thermal pressure of the electrons, and…
Ultracold Neutral Plasmas
Thomas C. Killian, Y. C. Chen, P. Gupta +6
Ultracold neutral plasmas are formed by photoionizing laser-cooled atoms near the ionization threshold. Through the application of atomic physics techniques and diagnostics, these…
Absorption Imaging and Spectroscopy of Ultracold Neutral Plasmas
T. C. Killian, Y. C. Chen, P. Gupta +6
Absorption imaging and spectroscopy can probe the dynamics of an ultracold neutral plasma during the first few microseconds after its creation. Quantitative analysis of the data, h…
Using Absorption Imaging to Study Ion Dynamics in an Ultracold Neutral Plasma
C. E. Simien, Y. C. Chen, P. Gupta +5
We report optical absorption imaging of ultracold neutral plasmas.Images are used to measure the ion absorption spectrum, which is Doppler-broadened. Through the spectral width, we…
