We propose a novel propulsion method that utilizes the Marangoni flow generated around laser-induced bubbles for the non-contact propulsion of objects in liquids. In this study, we performed numerical simulations using the moving mesh method to optimize the ejection force required for precise control. The analysis confirmed a jet flow with a maximum velocity of 0.1655 m/s for a bubble diameter of 0.1 mm, demonstrating that the flow around the bubble functioned as a driving force. In this presentation, we compare the analytical results with experimental data and report on the optimization of jet force control.
