Semiconductor microspheres are expected various application due to their spherical shape, and we have succeeded in synthesizing Si and ZnO microsphere by laser ablation in the air. This method is simple and can be applied to materials with light absorption. On the other hand, it is important to control the size and the arrangement of microspheres in application. In this study, we aim to control the flying direction of the microsphere synthesizing by optical vortex laser ablation in the air.
