I dont see the breakthrough. All light causes evaporation, even at near-zero heat. Every light ray has the possibility of knocking off a molecule of water, transfering enough energy to turn it into gas. If the angles are just right, the water molecule vibrating just the right way, it gets lauched off the surface to become gas. Whether it stays gas depends on other things, but i dont see how observing the process is anything new; Better defining the process but not worthy of the article title.
