Effects of Ambient Temperature on Laser-Induced Plasma in Bulk Water:
TLDR
The results suggest that the ambient temperature has great influences on laser-induced plasma, which needs to be taken into account in underwater LIBS measurement, especially on-site marine applications.Abstract:
Laser-induced breakdown spectroscopy (LIBS) has been successfully applied to ocean exploration, but the changes in marine environmental factors could have an important impact on the LIBS signals. T...read more

Pressure effects on underwater laser-induced breakdown spectroscopy: an interpretation with self-absorption
TL;DR: In this paper, the authors explored self-absorption to evaluate the pressure effects on laser-induced breakdown spectroscopy (LIBS) detection in the sea, and they proved that selfabsorption was significantly enhanced with increased pressure, and the severe inhomogeneity of plasma distribution might be the reason.
