THE WORKING PRINCIPLE OF MOPA FIBER LASER MARKER

Mopa fiber laser marker, also known as a pulse duration adjustable fiber laser marker, uses a fiber laser as the light source. The working principle of the Mopa fiber laser marker is based on the concept of selective photothermal interaction between the laser beam and the material being marked.

When the laser beam is focused onto the surface of the material, it heats up the material and causes it to change color or undergo a chemical change. The color or chemical change is typically permanent, making it an ideal process for marking and engraving on materials such as metal, plastic, and ceramics.

The Mopa fiber laser marker operates at a high frequency, producing short pulses of laser light that are typically measured in nanoseconds. By adjusting the pulse duration, the laser can be fine-tuned to interact with a wider range of materials and create different marking effects.

The laser beam is directed through a galvanometer scanner that rapidly moves the beam across the surface of the material being marked, creating a precise and accurate marking pattern. The Mopa fiber laser marker can be programmed to mark both text and graphic designs, making it a versatile tool for a variety of applications.

Overall, the Mopa fiber laser marker is a highly efficient and precise tool for marking and engraving a wide range of materials, and its flexibility in pulse duration adjustment allows for a wide range of marking effects.
