A NEW APPROACH TO DEVELOPING GAMMA-RAY LASER

A laser can greatly increase its power if the radiation comes from the atomic nucleus. The reason is that gamma rays, which are in the high-energy electromagnetic spectrum, come by their nature from the transition between excited to lower nuclear levels, as opposed to electromagnetic waves produced by atoms. The subject of this work is the development of a gamma laser (Graser). The first step is to excite the nuclei of certain isotopes to a higher-energy nuclear state. The excitation method used here is bombarding the nuclei with neutrons. Some isomeric nuclei, known as metastable, can remain excited for a relatively long time, which is what one is looking for. When an external source stimulates these excited nuclei, they can release their stored energy via gamma rays. The emitted gamma rays are modified to produce a coherent laser beam. This work traces the century-long achievement in the field of laser creation after numerous successful solutions and passing through the recoilless Mössbauer emission from the solid crystal lattice. However, scientists have not been able to create a Grasser due to controversial conditions. This article presents a new method, somewhat unconventional, designed to solve the so-called "Graser dilemma". This can be done by shifting the crystal lattice during the neutron bombarding. The technology has the potential to create extremely powerful lasers that can be used in various applications, including laser weapons.
