A theoretical study on the coupled electron-nuclear dynamics of HD⁺ molecular ions under ultrashort, intense laser pulses is performed by employing a well-established quasi-classical model. The influence of the laser carrier-envelope phase on various channel (H + D⁺, D + H⁺, and H⁺ + D⁺) probabilities is investigated at different laser field intensities. The carrier-envelope phase is found to govern the dissociation (H + D⁺ and D + H⁺) and Coulomb explosion (H⁺ + D⁺) channel probabilities. The kinetic energy release distributions of the fragments are also found to be sensitive to the carrier-envelope phase of the laser pulse. Our results are in agreement with the previously reported quantum dynamics studies and experiments.

通过超短激光脉冲的载波包络相位控制HD ⁺的超快动力学：准经典动力学研究

通过建立良好的准经典模型，对超短，强激光脉冲下HD ⁺分子离子的耦合电子核动力学进行了理论研究。研究了在不同的激光场强度下，激光载流子包络相位对各种通道（H + D ⁺，D + H ⁺和H ⁺ + D ⁺）概率的影响。发现载流子-包裹体相决定了解离（H + D ⁺和D + H ⁺）和库仑爆炸（H ⁺ + D ⁺）渠道概率。还发现碎片的动能释放分布对激光脉冲的载流子-包络相敏感。我们的结果与先前报道的量子动力学研究和实验一致。
