Optothermal generation, trapping, and manipulation of microbubbles.The most common approach to optically generate and manipulate bubbles in liquids involves temperature gradients induced by CW lasers.  In this work, we present a method to accomplish both the generation of microbubbles and their 3D manipulation in ethanol through optothermal forces.  The balance of the optothermal forces owing to the laser-pulse drives the 3D manipulation of the main bubble.
