| Research Abstract |
Laser ablation of metal targets in superfluid helium was performedwith a Q-switched Nd:YAG laser and provides a novel opportunity to obtain nano- and micro-particles with high crystalline quality . In addition, optical manipulation of fabricated metal nanoparticles was successfully performed in superfluid helium, so that only the smaller particles were selectively transported. On the other hand, we succeeded in the magnetic trap of superconductor particles due to Meissner effect.
