Abstract

A pulse optical fiber laser marking system comprises a master control part (10), a galvanometer module (23), a field lens module (24), a position detection module (21) and a drive module (22). The position detection module detects the distance from the surface of a workpiece to be marked as a detection point in real time. The master control part calculates displacement information about the galvanometer module and the field lens module needing to move according to the detection result, and generates a drive signal according to the displacement information. The master control part also produces a galvanometer control signal and a focusing control signal. The drive module drives the galvanometer module and the field lens module to move according to the drive signal. The galvanometer module controls a laser beam to deflect according to the galvanometer control signal. The field lens module focuses the deflected laser beam on the surface of the workpiece to be marked according to the focusing control signal.

Description

technical field [0001] The invention relates to the field of laser technology, in particular to a pulse fiber laser marking system. Background technique [0002] In 1960, American Maiman developed a ruby ​​laser at the Hughes Institute in California, which was the first laser in the world. The birth of the new laser technology makes the ancient subject of optics take an epoch-making step, and it is also one of the most important scientific and technological achievements in human history. In less than 50 years, lasers have been widely used in various fields of human life, including industrial processing, biomedicine, military, scientific research, measurement, etc. [0003] Compared with traditional solid-state and gas lasers, pulsed fiber laser is a relatively new type of laser. Its main advantages include: [0004] 1. The glass fiber does not need the strict phase matching of the incident pump light like the crystal, which is due to the wide absorption band caused by the ...
