| Outline of Final Research Achievements |
We proposed double pulsed laser ablation, which use two targets and two lasers. Atomic species ejected from targets, that is called plume, play important role to form nano-particles. We observed expansion dynamics of colliding two plumes. We systematically clarified effect of collision of two plumes. We found that the counter shockwave on the expanding plume is very important at higher background gas pressure. Our results are important to control structure of nanoparticle complex by using two pulsed excitation processes.
