Status report and biomedical applications of the institute of FEL, Osaka University

The Institute of Free-Electron Laser (iFEL) was established in April 2000 at Osaka University. The facility was constructed by the Free-Electron Laser Institute corporation (FELI) from 1992 to 1997. FELI demonstrated lasing in the spectral range from 0.28 to 20 μm. Efforts are still being made by Osaka University in order to extend the lasing range. In the operational period from April 2001 to March 2002, mid-infrared light of 5–20 μm was supplied for over 40 cooperative research programs on fields of semiconductor, bio-medical and environmental chemistry. An effort is ongoing to improve the property of the light. In this paper, the status of iFEL and some biomedical applications research are described.
