Control of Burst Intensification by Singularity Emitting Radiation (BISER)

Recently we successfully demonstrated controllable BISER in experiments with the J-KAREN-P laser using blade-induced shocks in supersonic gas jets. This resulted in significant improvement of the BISER source stability. Furthermore, the controllable BISER technique made an important breakthrough in the coherent x-ray source performance: the emission extended up to the keV spectral region. Additionally, the soft x-ray and XUV photon yield enhanced by orders of magnitude. In particular, we demonstrated a pulse with up to 1 uJ energy (10^11 photons) in the 60-100 eV spectral range within a 10^-2 sr acceptance angle.
