The ruby laser was utilized in laboratory settings and as a military rangefinder. Modern lasers are still used by the armed forces and in a wide variety of industrial and therapeutic applications. For example, Regenotech’s scientific consultant, Dawn Lipscomb, PhD, helped develop a laser to evaluate the inflammatory response to terahertz radiation at the Air Force Fort Sam Houston Lab. This particular frequency can detect the amount of water in a cell, which is helpful in determining the severity of a burn on the battlefield. In the hands of a field medic, this laser immediately determines whether or not a burn requires surgery.
