The LEOT curriculum was developed by the Center for Occupational Research and Development (CORD) in 1970-1974 with funding from the U.S. Office of Education. At that time many books on lasers were available for physicists and engineers. Those books contained the rigorous theoretical information needed to develop new designs and applications for lasers. The LEOT curriculum does not provide that kind of information.

The LEOT curriculum is written for the technicians who will build, modify, install, operate, troubleshoot, and repair lasers. Technicians are a vital link in the advancement of photonics technology. They are the workers in the laboratories, plants and fields who ensure that lasers, and other photonics related equipment, operate properly and reliably.
