Asymmetric frequency dependence of plasma jet formation in microwave resonator electrode

Plasma in supercritical fluid with densely populated clusters
In supercritical fluid (SCF) with dense population of stable clusters (โผ 1000 mmโ3; mean size โผ 200 nm), elongated plasmas are produced
along the optical axis of laser pulse (532 nm, 6 ns, 400 mJ, peak intensity โผ 1 TW/cm2).
The plasma has a strong afterglow with the lifetime up to 1 ยตs, increasing with the number density of clusters.
For argon SCF plasmas, the electron temperature and density estimated from continuum emission spectra are โผ 1 eV and โผ 10^21cmโ3, respectively, corresponding to a high Coulomb coupling constant of the order of unity.
The radial diffusion is weak, smaller than the diffusion length predicted by the one-component plasma theory for moderate to strong Coulomb coupling.
These observations suggest that the presence of clusters strongly affects the particle and energy transport processes.1
