| Research Abstract |
The aim of the research is investigation into techniques for a seeded free-electron laser (FEL). The Seeded FEL have advantageous features that output pulses are in principle fully coherent in both transverse and longitudinal axes. We researched a new seeded FEL method with a radial-polarized laser pulse for the seeding source of it. Then, the radial-polarized laser pulses, which are high-harmonic-generation, was tried to make Then, generating of the radial-polarization was tried for using the seeding light source. Moreover, we developed one of key schemes for seeded FEL operation which is a timing monitor system. It enables to observe a timing drift between electron-bunches and laser pulses with an electro-optic sampling technique.
