They develop, make, and test products. They may use computers to design, set up, monitor, and maintain fiber fabrication. Technicians work on military and space projects. They repair and adapt low-power lasers used in target tracking, ranging, identification, and communications. Laser holography is useful in the nondestructive testing of parts.
Holograms can reveal flaws in items ranging from tiny crystals to huge machines.
Technicians conduct these tests. Technicians may also design, build, use, maintain, and repair lasers in research laboratories. They carry out similar tasks in research and development and in data storage. In photo optics, technicians service lasers used in high-speed photography and mapping. In construction and mining, technicians work with lasers in surveying , measuring, testing, and alignment.
