When the laser field strength is comparable with the atomic unit field strength, many nonlinear physical phenomena appear. In recent years, intense laser pulse interactions with molecules have attracted much attention. It aims at exploring effects of the laser intensity on chemical reaction dynamics and at studying the wave packet structure of molecular exciting state.

It has given rise to a good deal of attention for the stability propagation and enhancing the propagation length of laser pulse.展开更多

In the photo-ionization process, the dissociative system will develop a time-dependent dipole moment and emit an odd harmonic of the incident laser frequency. In the past ten years, optical harmomc generation has attracted much attention. This is because high optical harmonics will undoubtedly lead to the development of bright, short-pulse and versatile sources of coherent radiation in the vacuum ultraviolet （UV） and X-ray ranges.
