Langmuir probe perturbations during in situ monitoring of pulsed laser deposition plasmas
Original language description
We explored the limitations of Langmuir probe (LP) as a technique for in situ PLD control by performing investigations on several metallic plasmas, expanding in various Ar atmosphere conditions. Sub-microsecond modulation was seen in the reconstructed IV characteristics attributed to non-equilibrium dynamics of the ejected charges. A perturbative regime was recorded for Ar pressures higher than 2 Pa, where ionic bursts were observed in the electron saturation region. This perturbation was identified as a plasma fireball. A non-linear multifractal model was developed to explore new regimes of the LP. The strange attractors characterizing each fireball were reconstructed and their evolution with the Ar pressure is discussed. Both short- and long-time non-linear behavior were correlated via probe bias and the pressure effect on the strange attractors defining the fireball-like behavior was investigated. A good correlation was noticed between the simulated data and experimental findings.n
