Transition of proton energy scaling using an ultrathin target irradiated by linearly polarized femtosecond laser pulses.
Particle acceleration using ultraintense, ultrashort laser pulses is one of the most attractive topics in relativistic laser-plasma research. We report proton and/or ion acceleration in the intensity… Expand
Stable generation of GeV-class electron beams from self-guided laser–plasma channels
Table-top laser-driven plasma accelerators are gaining attention for their potential use in miniaturizing future high-energy accelerators. By irradiating gas jet targets with ultrashort intense laser… Expand
Space-resolving flat-field extreme ultraviolet spectrograph system and its aberration analysis with wave-front aberration.
The Nam aberration of a flat-field extreme ultraviolet spectrograph system, composed of a varied line-spacing concave grating and a toroidal mirror, was analyzed by calculating the wave-front… Expand
Laser-driven proton acceleration enhancement by nanostructured foils.
Nanostructured thin plastic foils have been used to enhance the mechanism of laser-driven proton beam acceleration. In particular, the presence of a monolayer of polystyrene nanospheres on the target… Expand
Radiation pressure acceleration of protons to 93 MeV with circularly polarized petawatt laser pulses
The radiation pressure acceleration (RPA) of charged particles has been a challenging task in laser-driven proton/ion acceleration due to its stringent requirements in laser and target conditions.… Expand
Significant improvement in the efficiency and brightness of the J = 0-1 19.6-nm line of the germanium laser by use of double-pulse pumping.
We describe significant improvement in the efficiency and brightness of the J = 0-1 19.6-nm line of the neonlike germanium laser. A curved slab target was irradiated by two laser pulses of 100-ps… Expand
Simultaneous generation of ions and high-order harmonics from thin conjugated polymer foil irradiated with ultrahigh contrast laser
We report the manufacturing of an (ultra-)thin foil target made of conjugated polymer, poly(9,9′-dioctylfluorene-co-benzothiadiazole) (F8BT), and the simultaneous observation of laser-accelerated… Expand

An ion spectrometer, composed of a time-of-flight spectrometer (TOFS) and a Thomson parabola spectrometer (TPS), has been developed to measure energy spectra and to analyze species of laser-driven… Expand
Detailed space-resolved characterization of a laser-plasma soft-x-ray source at 13.5-nm wavelength with tin and its oxides
Space-resolved soft-x-ray spectra of laser-produced plasmas of pure-Sn metal and its oxides were measured in the spectral range 7–23 nm. We established a comprehensive spectroscopic database of the… Expand
Towards radiation pressure acceleration of protons using linearly polarized ultrashort petawatt laser pulses
Particle acceleration using ultraintense, ultrashort laser pulses is one of the most attractive topics in relativistic laser-plasma research. We report proton/ion acceleration in the intensity range… Expand
