graser

noun

1. A device for the coherent amplification or generation of electromagnetic radiation in the gamma ray wavelength by the use of excitation energy in resonant atomic or molecular systems.

   “The Russians are working on the graser. One B. V. Chirkov has published a theoretical study in the Soviet Journal of Experimental and Theoretical Physics. He thinks a very pure crystal, "pumped" with a powerful source of radiation (such a "hard" X rays), much as a ruby crystal is pumped with high-intensity light in one form of laser, could be stimulated to emit coherent gamma rays—pulses of high-energy radiation perfectly in step.”

   “Not lasers. Grasers. Gamma Ray Amplification by Stimulated Emission of Radiation.”

2. The beam of coherent gamma rays produced by such a device.

   “The graser beam melted through the far wall of the lounge, but luckily beyond that lay only sections of the complex containing the cargo runcibles, and there it finally spent its energy slagging the massive handler robots.”
