Anode In laser engraving, an anode serves as the positively charged electrode within an electrochemical cell or laser marking system that attracts electrons and ions during the engraving process. By providing a terminal for the flow of electric current and facilitating the oxidation reaction at the material's surface, the anode plays a critical role in generating electrical discharges, plasma formation, and chemical reactions required for material removal, etching, and marking. Different anode materials and configurations are employed in laser engraving systems to optimize engraving performance, control discharge characteristics, and ensure reliable operation across various applications and materials, including metals, ceramics, and semiconductors. |
