Femtosecond Laser Matter Interaction

激光诱导库仑成像技术利用超短激光脉冲的强场快速连续地从分子中去除许多电子。然后，分子被还原成其组成原子离子，这些原子离子通过静电力彼此排斥，并以与它们初始分离相关的能量飞散。如果我们可以使用时间和位置敏感检测器同时检测到所有这些离子，那么就有可能推断出分子的初始几何形状，并可能推断出分子在爆炸过程中的动力学。该研究计划将专注于通过帮助我们更好地理解物理来提高该过程的能力。

The technique of laser induced Coulomb imaging uses the intense field of an ultrashort laser pulse to remove many electrons from a molecule in rapid succession. The molecule is then reduced to its constituent atomic ions which repel each other with electrostatic force and fly apart with energy related to their initial separation. If we can detect all of these ions in coincidence using time and position sensitive detection then it is possible to deduce the initial geometry of the molecule and possibly the dynamics of the molecule during the explosion process. The research program will focus on improving the capabilities of the process by helping us to understanding physics better.
