Laser technology backdates to the 1950s when Townes invented the maser. His main aim was to find a gadget that primarily used light for the illumination of tissues and matter. These two technologies (lasers and masers) almost use the same physics ideology, which is the activation of atoms, hence providing them with more energy than they had. On the other hand, after these atoms lose energy, they return to their original energy state, whereby the energy released is in form of high frequencies. The main difference between masers and lasers is that lasers use light for illumination, whereas masers use radio energy during operation (Gilmore, 1962, pp.89-92)
