學門主題式計畫-極限頻段高能量超快雷射的發展(1/3)

In the past we have developed near infrared high field laser at National Central University. The peak power is as high as 100 TW. The laser was used in many high field physics experiments and considerable achievements were made that brought international recognition. In this project the goal is to overhaul the aging core facility, extending our capability to the extreme-UV and mid-infrared spectral ranges, pushing forward the development and innovation of advanced laser technology, and exploring cutting-edge applications. The first sub-project is to rebuild some critical part of the laser system and the cooling system, at the same time continue to develop extreme-UV sources based on high harmonic generation, extending its wavelength range, increasing its conversion efficiency, achieving frequency tenability, and exploring extreme-UV nonlinear optics. The second sub-project is to exploit our advantage in laser wakefield electron accelerator, shrinking the duration and emittance of the electron bunch, using betatron oscillation in plasma wake or undulators to develop table-top free electron laser, and applying it to high resolution x-ray imaging. The third sub-project is combining nonlinear optics and high voltage electron gun techniques to develop mid-infrared ultrashort pulse laser, with application in laser processing of organic films and prospective laser-driven proton accelerator. The budget request reflects our need for stable long-term support in facility maintenance and cultivation of future scientists and engineers.
