    "abstract": "We discuss the radiation generated by positrons channeling in a crystalline\nundulator. The undulator is produced by periodically bending a single crystal\nwith an amplitude much larger than the interplanar spacing. Different\napproaches for bending the crystal are described and the restrictions on the\nparameters of the bending are discussed. We also present numeric calculations\nof the spontaneous emitted radiation and estimate the conditions for stimulated\nemission. Our investigations show that the proposed mechanism could be an\ninteresting source for high energy photons and is worth to be studied\nexperimentally.",
