Gigahertz Amplification by Stimulated Emission of Radiation: Principles, Prospects, and Applications
Abstract The principle of stimulated emission, first introduced by Albert Einstein in 1916, has given rise to transformative technologies such as LASER and MASER, which revolutionized optics, communication, and precision measurement. Extending this principle into the gigahertz domain, Gigahertz Amplification by Stimulated Emission of Radiation (GASER) represents a bold theoretical frontier that seeks to harness coherent amplification of gigahertz-frequency waves. This dissertation investigates the conceptual foundations, comparative frameworks, and potential applications of GASER, situating it within the continuum of coherent radiation technologies. The study employs a multi-layered methodology: (1) a comparative theoretical analysis of LASER, MASER, and GASER principles, focusing on frequency scaling, coherence, and amplification mechanisms; (2) a literature synthesis of superconductivity, quantum tunneling, and phonon-mediated coherence as enabling pathways; and (3) a prospective ...
