What are the main parameters of the ultrafast laser marking control system?

Laser marking is currently one of the most widely used laser processing technologies. Its principle is to use a highly concentrated laser beam to instantly evaporate part of the material surface, forming an indelible mark. Laser marking has the advantages of fast speed, good texture, and high accuracy, and has been widely used in many industries such as packaging, advertising, and 3C electronics.

Ultra fast laser is a special type of laser, which has an extremely short pulse width, usually in the range of femtoseconds (1 femtosecond=10 ^ -15 seconds) or picoseconds (1 picosecond=10 ^ -12 seconds). The extremely short single pulse makes the processing range and method of the laser more controllable, allowing for precise processing of very fine processing tasks. Therefore, ultra fast laser is also commonly used for high-precision processing.

The laser marking control system is the control core of the laser marking machine, mainly responsible for controlling parameters such as laser power, galvanometer movement, focus distance, processing method, etc., to ensure the stability and accuracy of the marking process. The main contents of these parameters include:

Laser control: The control system can adjust and control the output power, frequency, and pulse width of the laser to adapt to marking tasks of different materials and processing requirements.

Motion control: The laser marking machine mainly adjusts the laser position by controlling the angle of the reflector through the galvanometer motor. The control system needs to control the galvanometer motor according to the input marking pattern, allowing the laser to move along the set path, thereby successfully completing the processing task.

Processing method: Operators can set corresponding processing times, processing methods, processing objects, and other parameters through the laser marking control system. After starting processing, the control system will automatically run according to these set parameters, achieving automation and batch production.

Production monitoring: The ultrafast laser control system is equipped with monitoring function, which can monitor the production and safety conditions in real time based on feedback from sensors or cameras. In the event of production errors or safety accidents, timely alarms are issued and the machine is stopped.

Due to the fact that ultrafast laser marking is mainly used for high-precision processing, the requirements for ultrafast laser marking control systems are higher compared to ordinary laser marking control systems, such as chips with better performance, optimized motion algorithms, more anti-interference measures, etc. Therefore, the price of ultrafast laser marking control systems will be much higher than that of ordinary laser marking control systems.
