We present the recent achievements in the ion acceleration experiment with the J-KAREN-P laser system [1] at Kansai Photon Science Institute, National Institutes for Quantum and Radiological Science and Technology (QST). The previous J-KAREN system enabled us to perform the high field physics experiments with a laser intensity of 1021 Wcm−2, where we successfully obtained energetic hadron beams [2,...
The J-KAREN-P laser facility [1] can provide FW peak power at 0.1 Hz. It is based on the generation of short pulses of 30 fs and energy of 30 J after compression. The contrast of the generated pulses is better than 1012 and the final focused intensity is higher than W/cm2. Such performance in high field science will give rise to the birth of new applications and breakthroughs, which include relativistic...
Almost fully stripped aluminum ion acceleration up to 12 MeV/u from the interaction between the ultra-intense short pulse high contrast laser and the micrometer thick foil target is presented.
We present the new regime of high-order harmonics generation by multi-TW femtosecond lasers irradiating gas jet targets. We describe new results concerning the off-axis XUV harmonics emission, angular distribution and source size.
Low ablation threshold ~ 10 mJ/cm2 for LiF dielectrics irradiated by ps XRL was observed. Spallative mechanism of dielectric ablation by short XRL pulses was proposed and explained experimental results.
The rapidly aging society in Japan has resulted in an increased demand for electric wheelchairs to enhance the mobility of elderly persons. However, the increased use of electric wheelchairs means an increase in the number of accidents related to wheelchair operation errors. The majority of errors involve the joystick interface because its controllability is highly sensitive and not very intuitive...
