In this work, the evaporation of a droplet on a superhydrophobic surface with micropillars induced by a focused infrared laser beam was visually investigated. The results showed that the droplet on the superhydrophobic surface presented a composite contact state. Upon laser beam irradiation, the droplet temperature rapidly increased due to the photothermal effect, which induced violent droplet evaporation. Due to the localized heating effect, the environmental temperature was hardly affected and the generated vapor condensed near the triple-phase contact line, forming numerous satellite droplets. Simultaneously, these condensed droplets coalesced with the mother droplet, which changed the droplet wetting state from Cassie to Wenzel state with respect to the increase of contact diameter. After the transition, the droplet evaporated in a constant contact radius mode (CCR), and the droplet temperature was stabilized at a relatively high level. Moreover, the influence of laser power and the geometry of the micropillars were also investigated. The results indicated that the droplet temperature increased with the input laser power but the extension of contact diameter was nearly the same. It was found that Increasing the width of the micropillar would reduce the air space between the micropillar, which facilitated the extension of the contact diameter. But when increasing the height and pitch, the situation was converse due to the growth and coalescence being suppressed.
