Excitation Excitation in laser engraving involves the process of providing energy to the laser medium to induce the transition of atoms or molecules to higher energy states, leading to the emission of laser light. Excitation can be achieved through various methods, such as optical pumping, electrical discharge, or chemical reactions, depending on the type of laser used. By controlling the excitation process, engravers can regulate the intensity, wavelength, and coherence of the laser beam, allowing for precise and controlled material processing in laser engraving applications. |
