Fluence Fluence, also known as energy density, is a measure of the energy delivered per unit area of the material surface during laser engraving. It quantifies the intensity of laser energy absorbed by the material, influencing engraving depth, speed, and quality. Engravers control fluence by adjusting laser parameters such as power, pulse duration, and spot size to optimize material processing and achieve desired engraving outcomes. Maintaining appropriate fluence levels is essential for preventing over-burn or under-engraving and ensuring consistent engraving results across various materials and applications. |
