Abstract

Optical vortex laser-induced forward transfer (OV-LIFT), in which light field with a helical wavefront is employed instead of a plane wave, enables the high-definition direct print of a variety of donor materials with high spatial resolution, however, its mechanism has not been fully understood yet. We herein demonstrate, for the first time, the numerical simulation model of OV-LIFT based on the simulation technique of thermo-fluid dynamics, including mass transport equation. Temporal evolution of the droplet ejection by the illumination of optical vortex pulse is successfully reproduced. Such numerical simulation model will enable the further improvements of OV-LIFT performances to develop advanced direct print technology for printed electronics, photonics and biotechnology.
