Abstract

We proposed a technique to manipulate a metal particle in glass optically. The glass in the neighborhood of the laserheated metal particle softened; hence, the metal particle migrated in the glass. In our numerical calculation, the temperature difference in the metal particle generated the inhomogeneous distribution of the interfacial tension between melted metal particle and softened glass. The inhomogeneous distribution generated driving force. In this presentation, the experimental temperature measurement by using emitted light of the migrating metal particle in glass was discussed. The temperature was approximately 2400 K and corresponded with the numerical calculated temperature reported before.
