Investigation of sum-frequency generation spectroscopy and its applications based on free electron laser produced by superconducting linear accelerator

In this study, primarily defining the general principle of infrared free electron laser (IR-FEL) produced by superconducting linear accelerator. Then sum frequency generation technique, its physics and the applications, at TARLA facility, are described to employ in non-linear optic laboratory (one of the experiement laboratories), will be set in the facility called Turkish Accelerator Center (TAC) Infrared Free Electron Laser that is still being set up with the support of the State Planning Organisation and is coordinated by the University of Ankara. TAC Collaboration is an inter-university collaboration including Gazi University.The design and requirements of non-linear optic laboratories to be establish in TAC-TARLA facility and the experimental tools that can be used in experiments to be done here is described in detail.Finally, the accelerator facilities that do researches with IR SEL obtained fromlinear accelerator by using sum frequency generation technique ?CLIO (France), FELIX (Netherlands)? are examined. The researches made by using sum frequency generation technique in these centers are summarized.Key Words : Superconducting linear accelerator, FEL, Sum-Frequency spectroscopy, Material and semiconductor researchs, Turkish Accelerator Center(TAC), TARLA Facility
