Abstract
Laser ablation of sintered SiO2:TiO2 targets using Nd:YAG lasers at fundamental (1064[Formula: see text]nm) harmonic generation in the air has been studied using optical emission spectroscopy. Exploring the spatial fluctuations in electron temperature ([Formula: see text]) and electron density ([Formula: see text]), there is a discussion of how laser energy affects electron temperature ([Formula: see text]) and electron density ([Formula: see text]). Laser energy has also been shown to affect the intensity and velocity of neutral and ion species. Using existing data and theory, the findings were confirmed following the local thermodynamic equilibrium (LTE) hypothesis. Plasma properties such as Debye length ([Formula: see text]), ([Formula: see text]) and plasma frequency ([Formula: see text]) were also studied in this study. Using a laser, we found that all plasma parameters were affected. In addition, the calculated inverse Bremsstrahlung absorption coefficients ([Formula: see text]) were altered.
