Calculation of universal scaling function for free-electron-laser gain
A variational calculation of free-electron-laser gain in the exponential regime, before saturation is presented using a dispersion relation incorporating the energy spread, emittance, and focusing of the electron beam, and the diffraction and guiding of the radiation. Rapid computation facilitates f...

Zusammenfassung: | A variational calculation of free-electron-laser gain in the exponential regime, before saturation is presented using a dispersion relation incorporating the energy spread, emittance, and focusing of the electron beam, and the diffraction and guiding of the radiation. Rapid computation facilitates free-electron-laser design optimization. Results are expressed in a universal scaled form. (Author) |
