Abstract

I studied stimulated pair annihilation, and its probability is obtained according to Feynman rules. I also noted how this effect tested the nolocality of quantum mechanics. SPA is used to propose a positronium annihilation laser by using relativistic electrons and positrons and a periodical static magnet to produce the stimulating radiation and secure the coherence. Since the magnet period is practically limited to 5 × 10^–3 m the minimum required energy is 10⁹eV, which produces a frequency of 10³⁰ Hz. Also, this kind of laser is tunable and an attempt is made to calculate gain that is not inversely proportional to frequency like free electron lasers. Finally, I also propose a tunable gamma-ray source using SPA.
