摘要:

The electrical properties of microwave-induced plasmas (MIPs), relevant to signal detection of laser-induced ionization, have been investigated. Direct current vs. applied voltage relationships have been characterized for both argon and argon-active nitrogen plasmas. Suppression of signal detection for laser-induced ionization in the active nitrogen plasma is similar to that encountered in flames in the presence of thermally-ionized Group IA elements.
