PROSPECTS OF RARE EARTH ELEMENTS TO CREATE A NEW GENERATION OPTICAL AMPLIFIERS

The article analyzes the possibilities of using production rare earth elements to create optical amplifiers are the main issues that need to be addressed in the further development of optical fiber amplifiers based on optical fibers doped with rare earth elements. The methods of doping ion optical materials used in optical fiber amplifiers, ion implantation process steps, estimation of the depth of penetration of the ions of rare earth elements in the surface layers of optical materials, it is shown that a method for plasma ion implantation of dopants of rare earth elements is one of the most promising and efficient methods.
