Title:Generation of intense high harmonics and its application to attosecond nonlinear optics
Speaker:Prof. Katsumi Midorikawa, Extreme Photonics Research Group, RIKEN, Hirosawa Wako, Saitama，Japan

Venue:Room A101 at WNLO
Abstract：
This lecture will present on the generation of intense soft x-ray pulses and its application to nonlinear multiphoton processes. Using such nonlinear processes, the temporal width of the 42 eV soft x-ray pulse was measured directly by an autocorrelation technique. A train of attosecond pulses was also characterized by interferometric autocorrelation using Coulomb explosion of molecules. Intense high harmonics produced by phase-matching technique enable the observation of these nonlinear optical processes.
