Laser-Driven Electron-Acceleration Technology Group will develop the compact, stable laser driven electron acceleration system, and its key technology towards the new generation of XFEL. Laser Acceleration Development Team proceed the R&D of GeV-class multi-staged Laser Wake-Field Acceleration (LWFA) with plasma photonic devices. Basic Laser Development Team will develop the compact power lasers based on these Tiny Integrated LAsers (TILA) to provide the extreme giant-power, and open their fruitful future of “Giant Micro-photonics” for the advanced electron accelerators.
