| 英文摘要 | in this paper, we theoretically investigate the effect of noise on the photoionization, the generation of the high-order harmonic and the attosecond pulse irradiated from a model he+ ion. it shows that by properly adding noise fields, such as gaussian white noise, random light or colored noise, both the ionization probabilities (ips) and the harmonic yields can be enhanced by several orders of magnitude. further, by tuning the noise intensity, a stochastic resonance-like curve is observed, showing the existence of an optimal noise in the ionization enhancement process. finally, by superposing a properly selected harmonic, an intense attosecond pulse with a duration of 67 as is directly generated. |
