Enhancement of long wavelength preheating in dual-beam laser induced breakdown spectroscopy

AIP Advances, 2018
Dual-beam laser induced breakdown spectroscopy (LIBS) is more sensitive than conventional single-pulse LIBS. A combined configuration of Nd:YAG and CW- CO2 lasers is used to improve the emission intensity of LIBS.

Biomedical applications of laser-induced breakdown spectroscopy (LIBS) [PDF]

SPIE Proceedings, 2015
LIBS has been proven to be a robust elemental analysis tool attracting interest because of the wide applications. LIBS can be used for analysis of any type of samples i.e. environmental/physiological, regardless of its state of matter. Conventional spectroscopy techniques are good in analytical performance, but their sample preparation method is mostly
