Introduction

Fiber lasers have become a revolutionary tool in the metal engraving industry, offering precise and efficient solutions for marking and designing on metal surfaces. This article delves into the detailed mechanism of how fiber lasers operate and the specific parameters critical for effective metal engraving.

Working Principle of Fiber Laser Engraving

Fiber laser engraving employs laser technology involving a solid-state laser medium. It utilizes optical fibers doped with rare-earth elements like ytterbium to amplify the laser beam. The laser beam, characterized by a high-intensity and small focal diameter, interacts with the metal surface by absorbing the light, which is then converted into thermal energy. This energy causes localized heating, melting, or vaporization of the metal, resulting in a permanent mark or engraving.

Specific Parameters and Numerical Analysis

Laser Power

Power levels of fiber lasers can range from 20W to over 1kW, with typical metal engraving applications using between 20W and 50W. The power must be chosen based on material properties and engraving depth required.

Wavelength

The most common wavelength used in fiber laser engraving is around 1070 nm, which is in the infrared spectrum. This wavelength is optimal for metal absorption, allowing efficient energy use for engraving.

Engraving Speed

Engraving speed can significantly influence the quality of the engravings. Typical speeds range from 200 mm/s to 2000 mm/s. Higher speeds can reduce engraving quality due to inadequate energy absorption, while lower speeds allow for deeper and more pronounced engravings.
