Multipurpose chemical laser, also known as MCL, is a type of laser that uses a chemical reaction to produce a high-energy light beam. Other terms that can be used synonymously with MCL include chemical laser, gas laser, and COIL (chemical oxygen-iodine laser). Additionally, some specific types of MCLs have their own names, such as HF/DF laser (hydrogen fluoride/deuterium fluoride laser) and HCl laser (hydrogen chloride laser). All of these lasers have various applications in areas such as defense, medical procedures, and industrial processing, and are characterized by their ability to perform multiple functions with a single device.
