“…Resonant laser ablation (RLA) and resonantly enhanced LIBS (RE-LIBS) are experiencing a renewed interest and many references are reported on these topics. 369,,–393 The main features of these approaches are minimal sample destruction and improved limits of detection. It will be shown that RLA and RE-LIBS are performed with much lower energy pulses from the ablation laser (which explains the minimal sample destruction) and that the excellent detection limits refer to the absolute rather than relative detection limit.…”

“…375 Enhanced atomic emission will also result from the resonant ablation process, and the effect has been exploited in hyphenated approaches such as laser ablation-microwave plasma emission and ICP-MS, 381 or as a variant of LIBS in which enhanced plasma emission is observed after resonant ablation with a tunable laser. 390,,–392 This process can indeed be called resonance fluorescence . In addition, two lasers can be used in an arrangement similar to the collinear or orthogonal dual pulse experiments (see previous section): in this case, one laser is tunable and the term resonantly enhanced LIBS is used.…”

Laser-Induced Breakdown Spectroscopy (LIBS), Part II: Review of Instrumental and Methodological Approaches to Material Analysis and Applications to Different Fields

2012

The first part of this two-part review focused on the fundamental and diagnostics aspects of laser-induced plasmas, only touching briefly upon concepts such as sensitivity and detection limits and largely omitting any discussion of the vast panorama of the practical applications of the technique. Clearly a true LIBS community has emerged, which promises to quicken the pace of LIBS developments, applications, and implementations. With this second part, a more applied flavor is taken, and its intended goal is summarizing the current state-of-the-art of analytical LIBS, providing a contemporary snapshot of LIBS applications, and highlighting new directions in laser-induced breakdown spectroscopy, such as novel approaches, instrumental developments, and advanced use of chemometric tools. More specifically, we discuss instrumental and analytical approaches (e.g., double- and multi-pulse LIBS to improve the sensitivity), calibration-free approaches, hyphenated approaches in which techniques such as Raman and fluorescence are coupled with LIBS to increase sensitivity and information power, resonantly enhanced LIBS approaches, signal processing and optimization (e.g., signal-to-noise analysis), and finally applications. An attempt is made to provide an updated view of the role played by LIBS in the various fields, with emphasis on applications considered to be unique. We finally try to assess where LIBS is going as an analytical field, where in our opinion it should go, and what should still be done for consolidating the technique as a mature method of chemical analysis.

“…Spectroscopic analysis has been shown to be an effective tool for measuring lead content. Resonant laser induced breakdown spectroscopy has detected Pb at concentrations as low as 8 ppm, 24 and absorption spectroscopy has detected lead down to 90 ng/g. 25 The remaining prominent minor components are aluminum, iron, magnesium, and nickel.…”

Spectral Emission Signatures from Cased High‐Explosive Charges

et al. 2021

Spectroscopic signatures of cased high-explosive charge denotations are examined using emission spectroscopy with sub nanometer resolution. Eleven distinct case materials are investigated for atomic features of their major alloying elements. Molecular features of case material combustion products are also investigated for five case materials. Emission is monitored within the 275–425 nm range for atomic features and in the 310–755 nm range for molecular features. Major alloying elements with concentrations greater than 5% are generally detected through atomic emission. Al, Cu, Fe, Mg, Cr, Mn, Pb, and Ni are all detected in concentrations less than 5%. Undetected elements include Zn, Nb, Ta, and V. Molecular emission from aluminum monoxide, titanium monoxide, and CN is measured for aluminum alloy, titanium alloy, and carbon fiber cases, respectively.

“…Several approaches to enhance the emission signal have been suggested, such as a double pulse LIBS, [3][4][5][6][7] a laser induced uorescence LIBS, [8][9][10][11][12][13][14] a resonant LIBS, [15][16][17][18][19][20] a spark-discharge LIBS, [21][22][23][24] and a glow discharge LIBS. [25][26][27] These methods allow inputting additional electromagnetic energy into the ablation plume by using secondary energy sources that employ an additional laser or spark discharged plugs.…”
