The dynamics of transient plasmas generated by ns laser ablation of Ag targets under various O2 gas pressures (10−5–10 Pa) were investigated by implementing angle‐ and time‐resolved Langmuir probe (LP) analysis and space‐ and timeresolved optical emission spectroscopy (OES). The effects of an O2 atmosphere on silver oxide formation and the ionic kinetics and the overall plasma energy were systematically investigated. Measurements performed in the LP floating regime revealed the presence of three‐ionic structures with kinetic energies varying from 0.8 to 350 eV, which can be tailored by the addition of O2. The timemodulated regime of electron temperature in the 0.5–3 eV observed for pressures higher than 2 Pa of O2 could be explained by the formation and dissociation of silver oxide molecules.
