Delving into the science of capillary effect for laser polishing

Laser polishing techniques offer promising solutions for enhancing surface quality in precision surface finishing. By harnessing laser beams, this method provides efficient and controllable surface treatment, which is crucial for achieving desired surface smoothness and optical performance. Central to this process is the capillary effect driven by surface tension, which facilitates fluid flow on solid surfaces. Despite advancements, challenges persist in predicting and controlling capillary flow due to its complex nature. This paper explores the role of the capillary effect in laser polishing, outlining fundamental principles, discussing influencing factors, and proposing strategies for optimizing polishing outcomes. Understanding and manipulating the capillary effect holds the key to unlocking the full potential of laser polishing, offering avenues for improving surface finishes and material properties across various applications.
