Nonlinear optical process in the XUV region is of paramount importance not only in the field of quantum electronic but also in ultrafast optics. From the viewpoint of quantum electronics, new features of the interaction between intense XUV photons and matters are expected to be revealed through observation of those nonlinear phenomena. On the other hand, those nonlinear processes in the XUV region is indispensable for progress of attosecond science including attosecond atomic/molecular physics and chemistry, because it is very useful for investigating ultrafast phenomena directly in attosecond time scale. Using high harmonic generation by intense femtosecond laser technology, we are pursuing extreme optical science including XUV nonlinear optics and attosecond physics/chemistry.
