| Research Abstract |
(1) Development of High Performance Infrared Free Electron Laser The mid-infrared free electron laser (MIR-FEL : with the wavelength coverage of 5-16 μm) reached the saturation lasing on September, 2000. Research programs with the FEL beam were started in May, 2001 after accomplishment of full coverage of the wavelength, and the stabilization of the optical power. Then, efforts were paid for promotion of programs such as digitalization of control system, installation of a remote system to control wavelength from user's rooms, 24-hour continuous operation and so on. On the other hand, although the far-infrared free electron laser (FIR-FEL : 300-1000μm) has already been installed, the lasing emission has not been observed yet. It was delayed because of our policy to set higher priority to the operation of MIR-FEL than FIR-FEL which share the RF power supply, the lasing experiment was left for next fiscal year.
(2) Development of basic technologies for the FEL applications A new original optical system for transporting the FEL light to user's room as a parallel beam was developed and installed for practical uses. For the use of FEL beam, a variety of apparatus were developed. Those were for ; multi-photon dissociation, nano-second time-resolved IR spectroscopy of solutions, pico-second pump/probe experiment, IR near-field scanning microscope, isotope separation experiment, and others
(3) Research programs with the FEL beam Research programs at FEL have been carried out aiming to open the new field of photo-science in the infrared region, and to promote in our country. Highlights of the research outputs were ; (1)basic understanding of the multi-photon excitation and reaction process of molecules, (2)success in separation of isotopes and an isomers through multi-photon excitation process, (3)development of molecular imaging and operation by using the IR near-field microscope, (4)multi-photon dissociation of biological polymer by introducing FTICR mass-spectroscopy.
