"Development of Ultrafast Spectroscopy and Reaction Studied by the Observation of Ultrashort-life Species and Transition States"

  Professor Takayoshi Kobayashi has made numerous seminal contributions in the broad area of ultrashort pulse lasers and ultrafast spectroscopy. His outstanding scientific work focused on the development of ultrashort pulse laser and its applications to ultrafast spectroscopy by realizing the transition-state spectroscopy, which is the long-desired dream of scientists to observe molecular structures during the excited-state relaxations and chemical reactions and even during molecular vibration. Hus group has been keeping the shortest record of visible pulse from 1998 for more than 13 years and reached 2.4fs in 2111. The reactions studied his group are cis-trans isomerization, proton transfer, oxidation, and Claisen rearrangement. Until their study of the real-time vibrational spectroscopy of bacteriorhodopsin, information of the structure of the transition state had been studied only theoretically.
  Prof. Kobayashi developed completely different methods of controlling reactions from conventional coherent control by the quantum interference using his new stabilization scheme of the absolute phase of ultrashort pulse. This method has three advantages over the feedback (FB) method developed by Hall and Haensch (Nobel Award in physics 2005), in such a way that (1) no need for FB electronics, (2) no need for octave spanning of spectrum (3) applicable to amplifier system.

Humboldt Research Award

"Development of ultrashort pulse laser and its applications to ultrafast spectroscopy"

  The award is granted in recognition of a researcher's entire achievements to date to academics whose fundamental discoveries, new theories, or insights have had a significant impact on their own discipline and who are expected to continue producing cutting-edge achievements in the future.

  Professor Takayoshi Kobayashi from the University of Electro-Communications in Tokyo is internationally well known for his outstanding research in the development of ultrashort pulse lasers and in the investigation of ultrafast processes in molecules. Using a parametric amplifier with a non-collinear configuration, his group could generate the shortest pulses in the visible spectral range (4.0 fs) at that time. He established transition state spectroscopy using vibrational real-time spectroscopy.
