Introduction to Fiber Laser Technology

Fiber lasers have emerged as a dominant technology for metal engraving due to their efficiency, precision, and versatility. Leveraging optical fibers doped with rare-earth elements, these lasers produce high-quality, coherent beams. The industrial adoption of fiber lasers has revolutionized the metal engraving sector, offering unparalleled durability and maintenance efficiency.

How Fiber Lasers Engrave Metal

Fiber laser engraving involves the use of a concentrated laser beam to remove material from metal surfaces, creating precise, permanent marks. This process is typically achieved by rapidly heating the metal to its melting or vaporizing point, resulting in a high-contrast mark. The wavelength of fiber lasers (typically around 1064 nm) allows for a high absorption rate in most metals, facilitating efficient energy transfer and minimal material wastage.

Parameters and Numerical Analysis in Fiber Laser Engraving

Several parameters significantly influence the quality and efficiency of fiber laser engraving, including:

• Power Output: Ranges typically between 10W to 100W for engraving applications. Higher power levels allow for deeper engravings or faster marking speeds.
• Pulse Frequency: Affects the resolution and finish of the engraving. Frequencies between 20 kHz and 100 kHz are common, with higher frequencies producing smoother finishes.
• Scanning Speed: Determines the time efficiency of the process, often set between 200 mm/s to 2000 mm/s, depending on desired engraving depth and resolution.
• Spot Size: Influences the precision of the engraving, typically ranging from 20 µm to 80 µm.

Numerical analysis indicates that optimal engraving is achieved at a balanced combination of these parameters, allowing for high-quality outputs with efficient energy use.
