Both classical theory and the quantum wavelet transform method are used to understand the physics of harmonics. By adjusting the carrier envelope phase of the fundamental field, the intensities of harmonic spectra increase and the harmonics in the plateau become regular. Attosecond pulses each with a duration of 58 as are obtained directly by compressing the harmonics, and with phase compensation an isolated attosecond pulse less than 30 as can be generated.展开更多

Angular distributions from Coulomb explosion are independent of the laser wavelengths and intensities, which means the explosion starts from the same electronic state. Angular distributions from dissociation channels in the 810 nm laser field broaden with the laser intensity. Lobe structures in angular distributions from Coulomb explosion and above threshold dissociation channels are reported. Fine structures in the distribution of internuclear distances are observed.展开更多
