Figure 6. Optically driven droplet “micro-catapult”.

(a) Sequence of four photographs during the process of formation of sessile droplet of dense p-NA solution with laser light “on” and its subsequent ejection by relaxation of deformed interface with laser light “off” (cf. also SM4). Numbers show the mutual positions of interface and droplet in function of time. (b) Detailed photograph showing stream of liquid ejected via interface liquid-gas and starting formation of a droplet over glass plate (see also SM5).
