非均匀 3 色激光场波形优化产生阿秒脉冲.

In order to obtain the optimal inhomogeneous laser waveform of harmonic emission, the optimal waveforms of three - color pulse under the positive and negative inhomogeneous effects have been found by solving the time - dependent Schrodinger equation. The results show that the optimal extended high order harmonic spectra can be obtained by choosing the best positive and negative laser waveforms under the positive and negative inhomogeneous effects, respectively. Finally, the pulse duration of 43 as pulse can be obtained by Fourier transform in the harmonic plateau region. [ABSTRACT FROM AUTHOR]
