Proposed Distributed Feedback Crystal Cavities for X-Ray Lasers

Abstract

The strong interest in the coherent generation and guiding of x rays is well known. Many papers have recently appeared treating different concepts of stimulated x-ray emissions, and x-ray guiding in thin films was achieved. Crystals were suggested as end reflectors to generate feedback. Here we suggest a different type of cavity using zeolite crystals that would guide the emitted x-rays and at the same time generate the necessary feedback for self-sustained oscillation.
