    CdTe is an attractive semiconductor material for applications in solid-state high-energy x-ray and γ-ray imaging systems. We have studied a laser doping technique for the fabrication to p-type layers. This technique is also suitable for the spatially patterned doping and can be applied in the fabrication of an integrated CdTe device for two-dimensional imaging systems. An iodine-doped n-CdTe epitaxial layer was grown on single-crystal CdTe(111) using MOCVD method. On the other side, p-type doping was demonstrated in the form of minute patterns using our laser-processing technique. This device showed clear patterns reproduced with spatial resolution greater than 101p/mm when mounted on a vidicon type X-ray camera tube.

    Phase conjugation mirror by stimulated Brillouin scattering(SBS-PCM) is very useful to compensate the wavefront distortion due to the thermally induced aberration and depolarization of average power solid state lasers. Basic properties of SBS materials are summerized and several applications are reviewed for achieving power scaling of solid-state lasers.

    An arbitrary manipulation of atoms will be a promising technique in the field of lithography and surface science. Here we introduce the "Atom Holography" technique which enables us to manipulate atoms in arbitrary positions and intensity distribution, using the wave-like behavior of atoms. This also enables us to manipulate atoms in mass instead of manipulating each single atoms. A large enough diffraction angle can be obtained using the micro-fabricated-structures that are used in the recent X-ray optics, since laser-cooled atoms have long enough deBroglie wavelength, such as sub-micrometer.

    The high pressure and density equations of state(EOS) of materials must be accurately known for inertial confinement fusion(ICF) experiments, astrophysics and other related fields. In order to measure the density directly and accurately, the precise and novel measurement technique has to be developed. X-ray radiography can be used to accurately measure density. Instead of ideal point source x-ray backlight, we have developed penumbral x-ray backlight imaging technique. we were able to obtain the convolution image and reconstraction the Target function.

    It is necessary to observe the uniformity of the imploding shell for investigating the relation between the implosion nonuniformity and disturbance to heating of the core plasma We propse a new technique of the multiple-exposure technique with a 2-Dimensional Sampling Image X-ray Streak camera(2D-SIXS) method for this purpose. We refined the principle, designed the diagnostic system, and developed a program to reconstruct a 2-D images automatically from a streaked sampling image obtained by 2D-SIXS method. Feasibility of this method has been demonstrated in the implosion experiments.

    An x-ray imaging system(i.e., imager) was developed to observe formation of hot, dense plasma created by intense laser. The imager consists of a two dimensionally bent Bragg crystal (Ge(311)) and an x-ray CCD camera to provide a monochromatic x-ray image of 3.67 keV with a 20 eV window. Spatial resolution better than 9 mm was confirmed for a view field of 500 mm. A new imager, for use in hydrodynamic instability measurements with 1.48 keV flash x-ray source, has been destined by using a ray trace code.

    In time-resolved spectroscopic T-ray imaging a waveform of a THz pulse is recorded from a sample at each pixel of the image. The result is a time-indexed set of THz images, a 'THz movie'. These THz movies can be mapped to images with various algorithms or 'display modes'. We demonstrate how display modes can map physical properties of a sample show and help to understand special effects and also provide an easy means of distinguishing between various sample materials.
