在强烈激光回答的线性地极化的飞米秒 410 和 820 nm 的 N 2 的破碎被使用印射技术的速度学习。在 410 和 820 nm 的 N 2 的不同行为被观察。动能分布和 410 nm 地里的碎片离子的尖分布在非浸透政体在激光紧张上显示出弱相关性,与在 820 nm 的盒子相对照。不同激动的电子状态,即,经由垂直刺激占据的 non-Coulombic 潜力,被建议在短波长在破碎起关键作用。
Fragmentations of N2 in linearly polarized femtosecond 410 and 820 nm intense laser fields were studied by using the velocity mapping technique. Different behaviors of N2 at 410 and 820 nm were observed. Both the kinetic energy distributions and angular distributions of fragment ions in 410 nm field show weak dependency on laser intensities in the non- saturation regime, in contrast to the case in 820 nm. Different excited electronic states, i.e., non-Coulombic potentials populated via vertical'excitation, are suggested to play crucial roles in fragmentations at short wavelength.
