Helium Neon Laser and its Uses in Medicine

Abstract

In this research, we discussed the laser, how it was developed, when it was discovered, what are the capabilities of the laser, the conditions for the occurrence of the laser, the principle of its operation, the characteristics of the laser, and finally the types of lasers. It also included the basic concept of the laser theory, its principle of operation, and the basic processes that occur during the interaction of the electromagnetic wave, as well as the basic processes in the electrical discharge of the gas. We also explained the properties of the laser, which include purity, high directionality, coherence toning, and also included the use of the laser in medicine. It included the helium-neon laser, its operating principle, components, advantages, and disadvantages.
