a device that produces a beam of gamma radiation, usually as an energy weapon n.
[< gamma ray amplification by stimulated emission of radiation, after laser]
Graser research might bring forth the ‘death ray’ that the laser falls short of, since gamma rays are dangerous to living tissue.
Victor let Talbot study them for a long moment, then said, ‘Not lasers. Grasers. Gamma Ray Amplification by Stimulated Emission of Radiation.’
‘How much broadside armament did it cost us?’ she asked after a moment. ‘All four graser mounts,’ McKeon replied, and watched her shoulders tighten slightly.
The first graser burst had hit the nose of the shuttle thirty seconds after the tactical attack siren had begun to shriek; barely enough time to throw off a cloud of ablative chaff, designed to dissipate the intital energies of the incoming gamma-ray photons.
The yields were about one hundredth of a crustbuster burst, which was sufficient to power a particle beam or graser with a five-light-second kill range.
We can repel your grasers and nasen beams.
The ship sensed some of her underlying mood: a target selection cursor ghosted briefly across the enemy glyphs, locking grasers onto the distant projected light cones of the enemy flotilla.
NIR lasers are not for them. They want xlaser and graser gear, trillions of colors per path, and trillions of paths.
Massive weapons turrets protruded from it out into space: housing racks of missiles as large as attack ships; thinking bombs whose prime purpose had been to fight their way to exotic-metal hulls and detonate; particle-beam cannons gaping like cavern throats; rail-guns that could fill nearby space with swarms of ceramal projectiles travelling at near-c; lasers, grasers, masers.
