We have carried out systematic investigations of x-ray radiation properties of relativistic cluster plasmas created by the action of superintense laser irradiation. We have also demonstrated diffraction from Si crystal using x rays from
1. Quantum emissions Quantum beams (high energy and short pulsed electrons, ions, and photons) are emitted from materials in femtosecond intense laser fields and are expected to be used for medial applications, compact accelerators, and dynamic imaging of materials. We have studied quantum emissions, especially on fast electrons, protons, and hard X-rays,… (More)
We propose a new pulse shaping technique for femtosecond laser pulses around 400 nm. We used sum-frequency conversion of broadband shaped pulses in a 1 mm thick BBO employing a noncollinear angularly dispersion geometry. By use of pulse shaping technique of femtosecond laser pulses, studies of ultrafast phenomena in matters, nonlinear optics, and various… (More)
The transient lattice deformation of laser-shocked silicon single crystal was studied by picosecond time-resolved X-ray diffraction with laser plasma X-rays. The shock-recovered samples were evaluated by reciprocal space mapping.
In this paper, we performed the femtosecond time-resolved X-ray diffraction on the 60-fs laser irradiated a CdTe single crystal and detected the coherent longitudinal optical (LO) phonon (5.07 THz) at Brilliuon zone center. The coherent LO phonon is also confirmed by using an optical reflectivity measurement
In this paper, we report femtosecond time-resolved measurements of coherent phonons in CdTe(111) crystal using transient optical reflectivity and X-ray diffraction with laser-plasma X-rays.
