The invention relates to a free charged particle laser (LPL) for producing coherent electromagnetic radiation in the X and gamma range, applicable to the research field, industry, medicine The free particle laser is characterized in that it uses an undulator (3) consisting of a crystal with periodic spatial variation (4) of the atomic planes so that the particle beam path has betatronic oscillations based on the channeling effect, in the conditions lambda u = lambda beta, lambda > L u where L u is the product lambda u N u and psi = psi c, to produce coherent X or gamma radiation and uses a free charged particle beam (2) generated by a particle accelerator (1)
