“Enhancing LIBS Signal Intensity in Deep Ocean Applications Using High-Pressure Helium Gas and Laser Optimization”

https://pubmed.ncbi.nlm.nih.gov/38113768

This study investigates the use of laser-induced breakdown spectroscopy (LIBS) in a high-pressure helium gas environment for deep ocean applications, and finds that increasing laser energy and shortening laser transmission distance can improve LIBS signal intensity in such environment.
