“…With 50 fs pulses, the total plasma intensity with double pulses of 20 µJ (220 µJ) was 100 times higher than the one with a single pulse of the same pulse energy (120 µJ), and 50 times higher than the one with a single pulse but with a doubled pulse energy (140 µJ). Our observations on ultrashort double pulse ablation have been confirmed in similar studies in [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36].…”

“…The analysis of our results and those obtained in [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36] has revealed the fundamental role of the electron-lattice relaxation time ( el .  1-10 ps) for laser ablation regime and the resulting double pulse LIBS-features.…”

“…Second, for larger interpulse delays, the atomized plume component is heated up by inverse bremsstrahlung, leading thus to an enhanced atomic emission intensity, as also reported by several authors [57,82]. Indeed, complementary analyses by optical emission spectroscopy [78] evidenced the increase of plume temperature and ionization degree. The observation of plume temperature increase was also confirmed by modeling [37].…”

“…Figure 7. Emission intensities of atoms (red squares) and NPs (blue squares) deduced from plume images (see Figure 6) vs interpulse delay for two laser pulses of 2Jcm -2 [78]. The approximation by a biexponential function revealed two characteristic times for the observed plume compositional changes.…”
