Description
Summary:In this report, we propose a new concept of coherent generation of /spl gamma/-radiation, the mechanism of which is the stimulated nonlinear coherent annihilation of electron-positron pairs in a strong laser field. In analogy with the effect of self-induced transparency in conventional nonlinear optics, the nonlinear oscillation regime arises at high laser intensities, in which inversion in the two-level system under consideration can be removed in one pass and the /spl pi/-pulse of coherent /spl gamma/-ray radiation is generated. Estimates show the scheme proposed is a promising high-brightness source of coherent /spl gamma/-radiation.
