Angle-resolved time-of-flight spectra of neutral particles desorbed from laser irradiated CdS

Ablation of CdTe with 100μs pulses from Nd:YAG laser: Velocity distribution of emitted particles

“…However, in spite of the similarity of the ablation conditions, he obtained the half-range M-B distribution from the TOF experiments. Among other II-VI compounds we are aware only of the results for CdS obtained by Namiki et al [4]. They also found that the velocity distribution is the half-range M-B, but the observed anomalous strong angular dependence of the stream density and energy seems to rule out the possibility that the stream could be described by the half-range M-B distribution.…”

“…In his work he used 100 lm pulses of a Nd:YAG laser and found that the particle velocity distribution is the full Maxwell-Boltzmann (M-B). Among other A 2 -B 6 compounds there are only the result obtained by Namiki et al [4]. They also observed the full M-B distribution.…”

Directional ion emission from thin films under femtosecond laser irradiation

“…3 The forward peaking nature of LA plumes has led to an angular dependence described by a cos p ͑͒ function, where p has been reported in a wide range of values from p = 25 in Ref. 4 to p = 106 for the modified function ͓a cos͑͒ + ͑1 − a͒cos p ͔͑͒ of Dang and Qin. 5 The cos p ͑͒ dependence on angular emission has broadly been accepted as an empirical relationship.…”

Monte Carlo simulation study of the effects of nonequilibrium chemical reactions during pulsed laser desorption

“…As a result of elastic collisions, the more energetic particles fly predominantly in the direction of the outward surface normal. 14,[21][22][23][35][36] Figure 6 shows that the angular distribution of the mean energy of atoms becomes less focused in the flow with chemical reactions than in the flow without them. Moreover, it can be observed that the total translational energy is higher in the flow with reactions, and that molecules are more energetic than atoms.…”
