Other uses are soon found, such as propelling objects into space and for weaponry of various levels of sophistication. With the necessary energy levels found in gravitational potentials of the planet’s core and mantle, the resulting 'graser' beams are initially employed to nudge the singularities somewhere safer. While attempting to remove micro singularities inadvertently introduced into the planetary mantle, it is found they can serve as mirrors. The idea of gravity lasers has been popularized by science fiction works such as David Brin's Earth (1990). Īs of 2019, there are no plans to construct a gravity laser. Several proposals involve exploiting the momentum transport properties of superconductors, where s-waves and d-waves couple distinctly to gravitational radiation. Alternately, a hypothetical gaser could simply be built with sufficient length to begin with.Īlternate design proposals involve free undulators akin to a free-electron laser. For a gaser, a large-scale, slowly spatially varying gravitational potential could act as a mirror (by the WKB approximation). In optical systems this can typically be created by mirrors, effectively making a larger optical path length. The lasing medium must be long enough for the radiation to persist and excite more of the same.This typically requires some type of pumping, such as optical pumping. The particles must be in an inverted population, where more are in the excited state than the ground state. ![]() This could be possible in a gaser by a stimulated analog of the Penrose process.
