Laser-Driven Micro-Ship and Micro-Turbine by Water-Powered Propulsion

In this paper, we report experimental demonstration of propulsion of 100‐weight object with only 668mJ/5ns YAG laser. This is made possible by water overlay structure and the effort to reduce the friction by putting the object on water surface or using a levitating system which we call on “air‐slider”. Furthermore, several water supply systems provided the repetitive propulsion. In addition, we found the laser‐driven micro‐turbine would provide an interesting application area in driving micro‐obstacle.
