Nonequilibrium Solvation of Excited Dipolar Solute, Its Relaxation Causing Fluorescence Stokes Shifts, and Mechanisms of Photoinduced Electron Transfer between Conjugate π-Electronic Systems DireccNoboru MATAGA1994 Volume 22 Issue 9 Pages 717-724
Published: September 29, 1994
Released on J-STAGE: February 26, 2010
JOURNAL FREE ACCESSNonequilibrium solvation of excited solute molecules and its relaxation which play roles of crucial importance in the exciplex chemistry are discussed in relation to the mechanism of the fluorescence Stokes shift in polar solution originally given by the Lippert-Mataga equation and also in relation to the classical electron transfer (ET) theory by Marcus. Mechanisms of photoinduced ET which have been elucidated by femtosecond-picosecond laser photolysis studies on the hydrogen bonding (HB) systems in a nonpolar solvent are discussed as an extremely interesting example of ET induced by a specific coupling with a slight proton shift in HB.View full abstractDownload PDF (967K) -
Solvation-Induced Changes of Electronic and Geometrical Structures of Inter-and Intra-Molecular Exciplex SystemsNoboru MATAGA1994 Volume 22 Issue 9 Pages 725-733

Released on J-STAGE: February 26, 2010
JOURNAL FREE ACCESSThe most important fundamental aspects of exciplex chemistry for unlinked donor-acceptor systems and also the systems linked by flexible chains or directly are discussed on the basis of femtosecond-picosecond laser photolysis studies especially with respect to the solvation-induced changes of exciplex electronic and geometrical structures.View full abstractDownload PDF (1092K) -

JOURNAL FREE ACCESSImaging plates containing photostimulable phosphorus materials have an ability to detect two-dimensional images in a wide wavelength range from X-rays to visible light. They have advantages of a high sensitivity, a wide dynamic range of more than five orders of magnitude, a fast processing time, easy aquisiton with computers, and erasability. In the present paper, some characteristics of the imaging plates with an emphasis on the responce for laser pulses are reviewed.View full abstractDownload PDF (1513K) -

JOURNAL FREE ACCESSA variety of laser surface processings (LSP) have been studied in the last decade, however, their application was in limited fields of industries. A number of new LSP techniques under development will find new applications in the near future.View full abstractDownload PDF (1732K) -

JOURNAL FREE ACCESSWe have constructed a long pulse dye laser for the applications of high resolutionspectroscopy, laser processing, medical use and so on. A smooth trapezoidal pulse whose full duration time as long as 0.5ms was obtained by employing a confocal cavity with short focal-length mirrors. The cavity enables us to compensate the thermal distortion of the dye solution caused by the strong flashlamp excitation.View full abstractDownload PDF (501K) -

JOURNAL FREE ACCESSA phase-conjugation with a carbon dioxide laser has been demonstrated by a linear optics using a Multidither Adaptive Optical System (MAOS) with a nine-segmented adaptive mirror. In this study, a retroreflective characteristics, which features the phase-conjugate mirror, was observed with an optical configuration with the double-pass phase-reconstruction scheme. The laser beam when being tilted with a maximum tilt angle of ± 80 μm rad was retroreflected with a high tracking accuracy of < 6 μm rad. In addition, the laser beam distorted with Ge three phase-plates was phase-compensated automatically with the phase-conjugate adaptive mirror. The laser beam was then converged within a nearly diffraction limit, and a high Strehl Ratio of > 0.8 was achieved. The converged beam patterns obtained at the focal point were agreed well with the theoretical analysis. These experimental results confirmed that the phase-conjugate wave was generated automatically by the linear adaptive optics.View full abstractDownload PDF (1047K) -
