Paser

A PASER (from the acronym of Particle Acceleration by Stimulated Emission of Radiation) is a source that emits electrons in a coherent beam. This process was demonstrated for the first time in 2006 at the Brookhaven National Lab by a team of physicists from the Technion-Israel Institute of Technology. ^[1]

Electrons from an accelerator pass through a carbon dioxide medium in a resonant cavity in which the electrons undergo millions of collisions with the carbon dioxide atoms and are accelerated in a coherent fashion. No heat is generated in this quantum energy transfer, thus all the energy transferred to the electrons is used in accelerating the electrons. The electron beam created from this process results in electrons that are highly collimated in velocity in comparison to other acceleration methods.
