“…The vaporized material flux from the radiated area of the target expands at supersonic velocity into the vacuum. Similar to the ion intensity variation shown in figure 3, the material ablation rate is also reported to decrease with an increasing number of laser shots fired at a target surface area [21][22][23]. The reduction in the ablation rate is ascribed to the formation of the crater.…”

Ions emitted from planar Al and Cu targets irradiated with a 1064 nm pulsed laser were investigated with the help of a time-resolving Langmuir probe. It was found that the intensity of the ions emitted from a target area rapidly decreases with the increasing number of laser shots, and seems to reach saturation after about 10 laser shots. The saturated intensity of Al and Cu ions was approximately 0.1 and 0.3 times the intensity of the respective ions measured at the first laser shot, respectively. The higher target ion intensity for the first few shots is thought to be due to the enhanced ionization of target atoms by vacuum-ultraviolet radiations emitted from the thermally excited/ionized surface contaminants. The reduction of target ion intensity with an increasing number of laser shots thus indicates the removal of contaminants from the irradiated surface area. Laser-cleaned Al and Cu surfaces were then allowed to be recontaminated with residual vacuum gases and the ion intensity was measured at various time delays. The prolonged exposure of the cleaned target to vacuum residual gases completely restores the ion intensity. Regarding surface contaminants removal, laser shots of higher intensities were found to be more effective than a higher number of laser shots having lower intensities.

“…The main advantages of the LIBS technique over other spectroscopic techniques and specialized equipment in the geological eld are low cost, easy maintenance, no need to prepare samples in advance, and the possibility of simultaneous detection of multiple elements. 6,7 These advantages are widely used in various elds such as geological exploration, [8][9][10][11][12] metallurgical analysis, [13][14][15][16][17] marine exploration, [18][19][20][21] cultural relic identication, [22][23][24][25] environmental testing, [26][27][28][29] and nuclear material detection.

“…One of the main goals of these studies has been to develop laser ablation methods and laser induced plasma spectroscopy as a tool for elemental analysis. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] An important application of such studies in which laser ablation based analytical techniques have been used is nuclear forensic investigations. 18,19 Laser ablation based mass spectrometry techniques are among the chief analytical approaches used in nuclear forensic investigations because they can provide highly accurate elemental and isotopic information while requiring less mass compared to alternative analytical methods available for such studies.…”

We demonstrate a Wiley-McClaren Time of Flight Mass Spectrometer modified to allow direct extraction of ions from a laser-induced plasma. Unlike many other methods that utilize mass spectrometry to investigate laser-induced plasmas, no collisional cooling or further ionization of the plasma is required prior to acceleration, allowing measurements of the plasma ion composition to be obtained directly. Furthermore, we show using the laser ablation of gadolinium as an example that we are able to obtain the translational energy distribution of the plasma directly and infer information about the relative composition of ions within different regions of the plasma plume. The approach is then applied to laser ablation of a uranium sample as a step toward probing the chemistry under conditions relevant to a nuclear fireball for nuclear forensics applications.
