Air plasma control and guiding using laser excitation of molecular metastable states Conference Paper uri icon


  • The methods of suppressing attachment and controlling instabilities in atmospheric-density air plasmas with high electron densities, based on the excitation of metastable molecular states, are discussed. Enhanced population of metastable states may stimulate ionization in both electron-molecule and molecule-molecule collisions, and accelerate electron detachment from negative ions. Metastable states could also define the path of arc formation, allowing external control of arc location and timing. Specifically, Raman excitation of the first vibrational level of oxygen molecule was done using a high power, two-color laser.
