Multi-dimensional optical and laser-based diagnostics of low-temperature ionized plasma discharges
Plasma Sources Science and Technology
In this paper, a review of work centered on the utilization of multi-dimensional optical diagnostics to study phenomena arising in radiofrequency plasma discharges is given. The diagnostics range from passive techniques such as optical emission to more active techniques utilizing nanosecond lasers capable of both high temporal and spatial resolution. In this review, emphasis is placed on observations that would have been more difficult, if not impossible, to make without the use of such diagnostic techniques. Examples include the sheath structure around an electrode consisting of two different metals, double layers that arise in magnetized hydrogen discharges, or a large region of depleted argon 1s4 levels around a biased probe in an rf discharge.

Two-dimensional mapping of electron densities and temperatures using laser-collisional induced fluorescence
Plasma Sources Science and Technology
We discuss the application of the laser-collisional induced fluorescence (LCIF) technique to produce two-dimensional maps of both electron densities and electron temperatures in a helium plasma. A collisional-radiative model (CRM) is used to describe the evolution of electronic states after laser excitation. We discuss generalizations to the time dependent results which are useful for simplifying data acquisition and analysis. LCIF measurements are performed in plasma containing densities ranging from ∼109 electrons cm -3 and approaching 1011 electrons cm-3 and comparison is made between the predictions made by the CRM and the measurements. Finally, spatial and temporal evolution of an ion sheath formed during a pulse bias is measured to demonstrate this technique. © 2010 IOP Publishing Ltd.
