Outline of Final Research Achievements

Prism-coupled　KBBF devices were developed by the tight optical contact of the boundary between CaF2 and KBBF with diffusion bonding. The light sources at 7 eV and 8 eV with these devices were supplied respectively to ultra high-resolution photoelectron spectroscopy of superconductive materials and to angle-resolved photoelectron spectroscopy measuring electronic states at 2-dimensional Brillouin zone. High-efficiency, large scale transmission gratings were developed and the wavefront distortion of the diffracted beam due to the bending of the grating were analyzed. A femtosecnd multi-color laser was developed by using these gratings for harmonic generation, resulting in the output powers of 0.5 TW at the fundamental (800nm) and 0.1 TW at the second harmonic respectively at a repetition rate of 1 kHz.. By applying dual broad band frequency doubling to this system, the output energy of 90μJ (45 fs) was obtained at the forth harmonic (220nm) .
