Laser: a luz que revolucionou a tecnologia

Abstract

Based on the resources of bibliographic research, this work discusses the Laser, starting with its meaning and its historical process. In order to further study in question, is necessary to make a clear and accurate survey of laser physics of taking into account their properties, along with transitions processes proposed by Einstein, where it show the need Inversion of Population through the study of theoretical bases in ruby laser and laser gas Helium-Neonico. Also are shown in laser varieties, showing, of course, the differences between them and some of the types of existing Lasers. Consequently are shown of its applications, seeking these the importance of this invention. Another highlight in point are the necessary precautions for the use of laser.
