“…As time evolves and for some range of pressures, at around 0.4 mbar, a sharpening of the plume appears. This plasma sharpening was reported in [27] by S. Lafane et al around 0.5 mbar and along with the sharpening, they observe a second splitting of the plasma into two components.

“…As the time evolves, the second component (the slower one) joins the first component because of the background gas braking of the latter, and the plume splitting disappears. The plume splitting has also been reported by several authors [27][28][29][30][31]. S Lafane et al observed by fast imaging during the laser ablatio n of Sm 1-x Nd x NiO 3 target in background oxygen pressure, the plume splitting at time delays for which the plume front still follows an almost free-plume expansion.…”

“…It is to be noticed that as the distances, the lower and the higher limit of time delays where the shock-wave model is According to Zel'dovich and Raiser [25], shock-wave formation becomes important when the mass of the displaced gas is comparable to the masse of the plasma (Mp). Assuming a hemispherical expansion of the plume, using the drag model and taking R sw as the front position at which the beginning of the shock-wave formation was observed, Mp was calculated in [27] …”

Abstract.We report on the presence of an interesting cross-correlation among the deposition parameters which are usually overlooked in the usual empirical approach used by pulsed laser deposition growers. The fast intensified-charge-coupled-device (ICCD) photography imaging studies of the plasma generated by the KrF excimer laser ablation o f Sm 1-x Nd X NiO 3 at x= 0.45 in the presence of oxygen background gases at different pressures i s r e p o r t e d .

Evidence of the strong influence of the expansion plasma regime was found which showed that it is not simply related to the overall reactive gas content. Our findings demonstrate that the optimization of the pulsed laser deposition parameters, such as gas pressure, should be perfo rmed a lso ta ki ng i n to acco u nt th e ch em ical p ress ure ind uc ed by t he s ubs tra te nature. The analysis of the experimental results allowed us to estimate the average deposition oxygen pressure for Sm 0.55 Nd 0.45 NiO 3 in the typical range used for Pulsed Laser Deposition (PLD) of complex oxides, showing that the higher is the deposition pressure, the better the crystallinity.

“…However a few works about the plume dynamics has been done [8][9][10]. Our findings join the previous results on the effect of the plume dynamics on the properties of the deposited film [11][12][13][14][15][16][17][18].…”

“…Among those properties, the films morphology was related to one of the most important plume parameter which is the plume stopping distance (R st ) [13,14,16,17]. This latter quantity could be obtained by fast imaging [9,[19][20][21]. Beyond the stopping distance, the plume intensity drops dramatically and a diffusion process of the ablated species into the ambient gas takes place [19,22].…”
