Vectorial flow of phase-separated droplets in a mixture of water/organic solvent generated by a focused laser

It is well known that a focus laser generate attractive and repulsive force. Focus laser induce flow of springing out droplet in water/organic solvent mixture of two-phase. We report that behavior of droplets are changed by condition of laser power focused. We observed that movement distance and initial velocity of the droplet is related to laser power. By the result of analysis, velocity which droplets spring out from focus point attenuated by surrounding medium resistance. Therefore, velocity of springing out are affected by laser power and medium resistance. And we observed that movement distance of droplet changes by reason of laser power.
