Imaging of the behavior of atoms and emissive species in laser-induced forward transfer process

Abstract

Summary form only given. Laser-induced forward transfer (LIFT) is a technique for fabricating micron-sized thin film, and can be applied to the mending or writing an electrical circuit or the fabrication of micro machine etc. The process of LIFT has not been well understood, so it has been optimized by a trial and error method. To understand and control the process, understanding of the particle behavior in LIFT process is essential. In the experiment, the behaviors of atoms and emissive species in LIFT process were firstly visualized by two-dimensional laser-induced fluorescence (2D-LIF) and imaging of thermal radiation. To observe the micron-sized LIFT process, a long-working distance microscope was used.
