摘要：A pulse-modulated argon surface wave plasma generated at atmospheric pressure is characterized by means of temporally resolved optical emission spectroscopy (OES). The temporal evolution of the gas temperature, the electron temperature and density, the radiative species of atomic Ar, and the molecular band of OH(A) and N-2(C) are investigated experimentally by altering the instantaneous power, pulse repetitive frequency, and duty ratio. We focused on the physical phenomena occurring at the onset of the time-on period and after the power interruption at the start of the time-off period. Meanwhile, the results are discussed qualitatively for an in-depth insight of its dynamic evolution.
