1. Having developed quantum generators called 1аzers, scientists are looking for practical use for a new kind of ray which is millions of times brighter than the Sun.
2. Semiconductor lazers are able to transform electric energy directly into light wave energy, this property of semiconductor lazers opening up new possibilities of producing extremely economical sources of light.
Lazers are known to have found an application in the printing industry.
3. Light waves are now believed to be due to the motions of electrons themselves within the atoms.
