报告摘要:In science and technology, one always needs light sources over a broad spectral range. To study dynamics at the timescale of the motion of electrons and atoms in materials, light pulses of femtoseconds to attoseconds are required. In this talk, I will give an overview of what scientists have been able to achieve in new light sources in the last twenty some years utilizing the extreme nonlinearity of the interaction of intense lasers in a gaseous medium. The basic idea behind high-order harmonic generation and the subsequent emergence of attosecond pulses will be reviewed. Then I will present recent progress and challenges that are waiting for solutions.
