![]() ![]() Encouraged by Boyle’s research, Peter Franken of the University of Michiganīegan similar experiments, but his early attempts to create an acceptable plasma were unsuccessful. ![]() Plasmas because, “good plasmas were only formed in air, not in inert gases or nitrogen,” which Boyle was testing. Boyle of Bell Telephone Laboratories used a ruby maser pulse to generate The LIBS concept began with the creation of the maser and laser in the late 1950s and early 1960s. You point the laser and get the data back.” History And you don’t have to do anything to the sample. LIBS features an “all-optical technique.” Frank De Lucia, a research chemist at the Army Research Lab at Aberdeen Proving Ground in Maryland, which has been a leader in LIBS development, said, “It allows you to do standoff-some people have identified materials out to distances of 100 meters. The spectrometer then analyzes and sends the results to the database, which could be a laptop computer, for rapid identification. Included in the plume are the atomic constituents of the target, which are revealed as the resultant, excited microplasma cools. The plasma contains a smorgasbord of scientific information, and the process provides multielement detection (solid, liquid or gas). The pulse laser ablates, or vaporizes, a small portion of contaminated material that, when enough energy is applied, becomes plasma. LIBS partners two tools of modern photonic technology, the pulse laser and the spectrometer. Armed with this information, ground forces sidestep the hazard and continue their mission without the hindrance of protective overgarments and gas masks. Within seconds, the probe ablates and analyzes contaminants on these surfaces and localizes the hazard. ![]() The probe scans for chemical warfare agents on nearby asphalt, soil, concrete and vegetation. Consider the following scenario:Ī mounted LIBS probe on a Stryker vehicle enters a highly contaminated warfare area befouled by unknown, potentially dangerous, toxic chemicals capable of doing great damage to incoming troops if left untreated. government, and an important prospective tool in that fight is laser-induced breakdown spectroscopy, or LIBS. Keeping technology one step ahead of the bad guys is an important mission of the U.S. ![]()
