Research topics

1. Laser-driven quantum beam geneartion

We study on the generation of quantume beams such as high-energy ions, electrons, X-rays etc., which are accelerated by a high electric fields when a high-peak power, short-pulse laser is foucsed to a small spot.
Carbon ions are of interest for downsizing existing cancer therapy machines and we are developing a laser based injector under the new concept "Quantum Scalpel". Heavy ions are also important for nuclear physics. 

Laser electron acceleration is studied to realize a compact X-ray free-electron laser system and a compact gamma-ray source for science and industry.

2. Ultra-High Field Science

We achieved a focused intensity of ~1022 W/cm2, which was the highest intensity in the world in 2017. With this intensity or higher, we explore new phenomena explored theoretically, numerically, and experimentally. 

3. Upgrade and Improvements of J-KAREN-P Laser

In collaboration with Advanced Laser Group, we continuously improve and upgrade the performance of J-KAREN-P laser. The J-KAREN-P laser is based on double chirped pulse amplification (CPA) to produce high-contrast, high-intensitiy laser pulses at 0.1 Hz.
