“…The impacted masses and the element ratios were measured by total reflection X-ray fluorescence after extraction and disintegration of all impacted particles and the addition of an internal selenium standard. Note that femtosecond LA in argon at atmospheric pressure yielded a fine aerosol distribution similar to that produced in helium, representing in total the true composition of the sample (6). It is interesting that the total impacted masses in femtosecond LA of brass in atmospheric helium and argon were in agreement with the masses removed from the craters within the experimental error.…”

“…2,5 When ultrashort laser pulses are applied instead of nanosecond laser pulses, the stoichiometry ͑e.g., of nanoparticle alloys͒ is less altered during the conversion of the bulk material ͑alloy͒ into nanoparticles. 6 Within the class of ultrashort pulsed lasers, it has been shown that high repetition rate picosecond lasers are advantageous compared to femtosecond lasers if the total thermal load produced by laser irradiation can be redistributed across a larger area. 7 In the case of laser ablation in a liquid flow, the thermal energy is dissipated into the liquid and drained by the flow, therefore it can be advantageous for the generation of colloidal nanoparticles.…”

Fabrication of silver nanoparticle colloids using ultrashort pulse laser ablation in water is studied. Ablation in liquid flow improves the reproducibility and increases the nanoparticle productivity by 380% compared to stationary liquid. Femtosecond laser ablation in water is 20% more efficient than picosecond laser ablation, but due to higher picosecond laser power (higher repetition rate), the nanoparticle productivity at the same pulse fluence is three times higher for picosecond laser ablation. With picosecond laser pulses, the maximum productivity of 8.6μg∕s is achieved at a pulse energy of 110μJ and repetition rate of 50kHz.

“…[14][15][16] With the introduction of ultra-short laser pulses in the picosecond (ps) and femtosecond (fs) ranges, a large interest in investigating the advantages offered by these laser sources for spectrometric applications, such as LIBS, has been developed both in single or double pulse approaches. 14,[17][18][19][20] The physical mechanisms involved in ultrashort fs laser ablation differ from those taking place with nanosecond (ns) pulses. Because of their very short duration, fs pulses do not interact with the resulting plasma; thus the absorbed laser energy is fully deposited into the material at the solid density, with little thermal diffusion while the pulse is on.…”

In the present study, a historical set of Late Roman glasses coming from a recently unearthed graveyard located in the small city of Cubas de la Sagra, within the Madrid region (Spain) was compositionally analysed using different techniques such as ultraviolet-visible (UV-Vis) and laser induced fluorescence (LIF) spectroscopies, X-ray fluorescence (XRF) and laser induced breakdown spectroscopy (LIBS). LIBS results, recorded upon nanosecond (ns) and femtosecond (fs) laser irradiation, served for identification of major glass components (to classify them into main historical glass groups) and of minor components (e.g. chromophores, decolouring agents and degradation products). Quantitative information regarding these components was obtained on the basis of calibration curves obtained using glass certified standards and local standards. We have demonstrated that LIBS serves for the noninvasive/micro-destructive, quantitative chemical characterization of most of the analysed historical glasses. Furthermore, this work establishes a comparison between LIBS analysis of glasses in the ns and fs regimes on one hand, and on the other hand with the results obtained 2 using XRF. The procedures and protocols here proposed can be applied for in-situ study of historical glass collections, regardless of their size, provenance and chronology.
