| dc.description | The dynamic process of H<sub>2</sub><sup>+</sup> in intense ultrashort laser pulses with intensities of 10<sup>14</sup> ∼ 10<sup>15</sup> W/cm<sup>2</sup>, wavelength of 532 nm and duration of 22 fs is theoretically investigated by using collinear model and numerically solving the time-dependent Schrödinger equation. The results show that: (1) the dissociation and dissociative ionization compete each other in the case of intensities between 2.5 × 10<sup>14</sup> and 4.0 × 10<sup>14</sup> W/cm<sup>2</sup>; (2) both the dissociation and the dissociative ionization are much smaller and appear at about 5 cycles (≈9 fs) later than the ionization. In addition, we estimate the spectrum of high harmonic generation and find that the well-known cutoff rule is invalid for the ultrashort laser pulse (e.g. the duration ≤ 25 fs), because the shorter pulse can produce higher order harmonics than the longer one. |
