We study a self-seeded high-gain harmonic generation(HGHG) free-electron laser(FEL) scheme to extend the wavelength of a soft X-ray FEL. This scheme uses a regular self-seeding monochromator to generate a seed las...

A simple analysis is given for the optimum length of undulator in a self-seeding free electron laser (FEL). The obtained relations show the correlation between the undulator length and the system parameters. The pow...

In order to meet the requirements of the synchrotron radiation users, a fully coherent VUV free electron laser (FEL) has been preliminarily designed. One important goal of this design is that the radiation wavelengt...
