Laser-aligned carbondisulfide (CS2) molecules are singly ionized by multiphoton absorption from intense, linearly polarized 25 fs laser pulses. The angular distribution of the photoelectrons exhibits a significant dependence on the angle between the polarizations of the aligning and ionizing laser fields. The widely used strong-field approximation predicts angular distributions in qualitative agreement with the experimental data but fails at a quantitative level.
激光对准的二硫化碳（CS₂）分子通过强的、线偏振的25飞秒激光脉冲的多光子吸收被单电离。光电子的角分布表现出对对准激光场和电离激光场的偏振之间夹角的显著依赖性。广泛使用的强场近似预测的角分布在定性上与实验数据一致，但在定量水平上失败了。
