| Popis: | We analyze the general class of constant period free-electron lasers (FELs) based on single-pass linear accelerator technology. The emittance and energy spread of the electron beam used to drive an FEL must be chosen to match the acceptance of the FEL wiggler. This acceptance determines the attainable current, and the current determines the gain and power output. For an optimized system in which the optical mode size in the interaction region is minimized, the gain is found to be independent of the laser length, while the efficiency and power output scale as the inverse and inverse cube of the length. Very high power output and good efficiencies are predicted. |
