Abstract

Using a high-power laser, Gekko XII, at Institute of Laser Engineering, Osaka University, we carried out a acceleration experiment of projectiles. We observed the acceleration of glass spheres with a diameter of 100 micro-meters. The glass spheres were accelerated to ~ 13 km/s. Also, we observe a CaO line in the spectrum of self-luminous impact vapor.
