“…We report on the systematic experiments characterizing the IR-induced increase of the corresponding critical velocity. In Paper II, 53 we present a comprehensive numerical model that elucidates the strong coupling between fluid flow, heat transfer, and contact line dynamics. In combination, the experimental and numerical results allow to determine the dominant mechanisms behind the IR-induced enhancement of the contact line mobility.…”

The shape of a droplet moving on a solid substrate is largely determined by the mobility of its contact line. Above a certain critical velocity, the droplet typically disintegrates and leaves residual liquid behind. We studied experimentally how localized infrared laser illumination can stabilize it against the progressive loss of liquid. We systematically varied the substrate velocity, the laser power, and the laser spot position and found that the critical velocity of the droplet can be substantially increased. These results are potentially important for increasing throughput in immersion lithography systems. V C 2016 AIP Publishing LLC.
