冷大气等离子体的脉冲激发通常被认为与主流正弦激发相比提供有价值的益处。然而，脉冲和正弦大气等离子体的直接比较仍然很少（如果有的话），因此不确定脉冲激发是否有利于任何显着优势。在这封信中，我们报告了一个比较研究的脉冲和正弦的冷大气等离子体射流通过电气特性，气体温度测量，和光学检测的反应等离子体物种。示出了脉冲激发的示例，以将电能消耗减少12倍，用于产生相同量的氧原子。
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.
