“…As a consequence, the interest in this field has produced a very large number of publications and the presentation of a large amount of spectroscopic information. 296,,–342 Fortunately, several very informative reviews and key papers have been written by leading groups in this field, in addition to a few modeling papers (see, for example, Babushok et al, 22 Noll et al, 307 Scaffidi et al, 325 Mao et al, 317 Colao et al, 301 Corsi et al, 306 Piñon and Anglos, 335 De Giacomo et al, 26,333 Bogaerts et al, 165 and Rai et al 167 ).…”

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.

“…Such values reveal that the gas number density inside the laser plasma in typical LIBS conditions is similar to the density of gas at room temperature at about 50 torr pressure. 67 As displayed in Fig. 4, particle number density and pressure show different proles.…”

“…As an order of magnitude, this result is in agreement with calculations carried out in ref. 67. Later, Cristoforetti et al found out that DP irradiation produces a signal enhancement (for species ablated from the target) only for ambient pressure values higher than about 100 torr.…”
