Paper Abstract

We report the first experimental evidence for direct particle acceleration by stimulated emission of radiation (PASER) namely, energy stored in microscopic cavities such as molecules, that otherwise may be used to amplify radiation, may be directly utilized for acceleration of a train of electron micro-bunches. In the framework of this proof-of-principle experiment, conducted at the Brookhaven National Laboratory, a 45MeV electron macro-bunch was modulated by its interaction with a high-power CO2 laser pulse, within an adequate wiggler, and then injected into an excited CO2 gas mixture. The emerging micro-bunches experienced a 0.15% relative change in the kinetic energy, in a less than 40cm long interaction region. Both the fundamental frequency of the train of micro-bunches and the active medium main resonance frequency are matched. This proof-of-principle experiment demonstrates, for the first time ever, the feasibility of coherent collisions of the second kind i.e., a particle analog of the laser.
