AMPLIFIER OF ELECTROMAGNETIC WAVES IN THE OPTICAL RANGE

摘要

Amplifier of electromagnetic :Waves in the optical range with multiple passage of the amplified signal through the medium, whose excited state is maintained by pumping system;distinguished by the fact that in order to expand the experimental possibilities during measurements, the amplifier is designed in the form of a closed-ring dielectric-fiber waveguide, each fiber with a small or negative coefficient of absorption and a Coating with a reduced dielectric constant;the input and output of energy is accomplished by optically switched light guides.
