摘要：

We have investigated the possibility of coupling the FEL optical beam into an external cavity. The resulting buildup of optical energy in the cavity offers several advantages. First, the sensitivity of the stored energy to source instabilities makes the external cavity a powerful FEL diagnostic. The dependence of the stored energy on several important instabilities will be discussed, as will plans for actually quantifying these instabilities with the external cavity. Second, a large amount of energy can be accumulated in the external cavity. Outcoupling this energy can significantly increase the micropulse energy delivered. Three possible outcoupling schemes will be discussed: "enhanced" outcoupling, photo-activated cavity dumping, and electro-optic cavity dumping.
