Pulsed excitation of cold atmospheric plasmas is commonly believed to offer valuable benefits compared to the mainstream sinusoidal excitation. However, direct comparison of pulsed and sinusoidal atmospheric plasmas remains few, if any, thus casting an uncertainty of whether pulsed excitation facilitates any significant advantage. In this letter, we report a comparison study of pulsed and sinusoidal cold atmospheric plasma jets through electrical characterization, gas temperature measurement, and optical detection of reactive plasma species. An example of pulsed excitation is shown to reduce the electrical energy consumption by a factor of 12 for producing the same amount of oxygen atoms.

- Dynamics of a guided streamer (‘plasma bullet’) in a helium jet in air at atmospheric pressure (2013, background): “…in the discharge is a few watts (Laroussi and Lu 2005, Teschke et al 2005); the gas temperature in the plasma jet is essentially ambient and there is a rich, electron-driven plasma chemistry in the mixing layer between the helium jet and the surrounding air (Laroussi and Lu 2005, Walsh et al 2006).”
- Surface modification of polymeric materials by cold atmospheric plasma jet (2014, background): “Plasma jets, or plasma plumes are a kind of atmospheric pressure gas discharges where the plasma (usually obtained from a noble gas) is extended beyond the plasma generation region into the surrounding ambience [4,6,7].”
