Amplitude Amplitude in laser engraving represents the maximum displacement or height of a laser beam's oscillation as it propagates through space or interacts with a material surface during engraving. It measures the strength or intensity of the laser beam's electric or magnetic field and influences the energy delivered to the material, affecting engraving depth, resolution, and quality. Controlling the amplitude of the laser beam through modulation techniques, such as pulse width modulation or amplitude modulation, allows operators to adjust engraving parameters and achieve desired material effects, including surface ablation, etching, and marking, across a wide range of substrates and applications. |
