Abstract
In this paper, we demonstrate an atmospheric-pressure nonequilibrium Ar microplasma array confined inside photonic crystal fiber for the first time. The diameter and the length of each microplasma plume are 3.4~\mu \textm and 2 cm, respectively. The electron density evaluated from the Stark effect of Ar spectral line is up to 8 \times 10^16 cm ^-3 . The electron temperature calculated by the Ar collisional-radiative model is 0.85 eV, while the gas temperature obtained by fitting the N2 rotational spectrum is 500 K. [ABSTRACT FROM AUTHOR]
