Abstract
A method using a laser to propagate a laser beam through an optically-transparent medium, wherein the laser has a power level beyond a critical value P, and wherein the laser beam interacts with the optically transparent medium to generate a laser-induced plasma filament (LIPF); and adjusting the power level to qualitatively detect chemical components within the optically-transparent medium.
