Towards compact laser-driven terawatt x-ray source
Year: 2025
Type: conference-paper
Abstract: We present our recent experimental results obtained with the J-KAREN-P laser. We demonstrated BISER in the XUV region (60-100 eV) with ~10 μJ pulse energy and >10^12 photons/pulse. Here, the spectral range and acceptance angle were limited by a small-diameter XUV mirror. Based on the angular distribution measured earlier, this indicates possibility of ~100 μJ BISER pulses emitted in a wider angle. The measured full bandwidth exceeded keV, corresponding to sub-10-attosecond transform-limited pulse duration and potentially terawatt x-ray pulses.
