Five applications of ultra-stable pulsed fiber lasers

The birth of pulsed laser technology is an important breakthrough in the history of laser development. It has been widely used in many industries and has made great contributions to the upgrading of manufacturing and the promotion of laser technology.

Chuangxin Laser has a profound technological accumulation in the field of pulsed fiber lasers. At present, it has a complete pulsed fiber laser product system, which can meet the needs of many industries for different processing applications.

1. Can mark

Pulsed fiber lasers are an ideal choice for marking the majority of electronic consumer products and industrial products. They have the advantages of good marking quality, fast speed, and high flexibility. They can be used for quality control traceability, anti-counterfeiting, product identification, etc.

The laser used by Chuangxin Laser for marking has good beam quality (M2＜1.3) and finer marking effect; wide pulse width (2-350ns), suitable for more materials; wide frequency range (1-2000KHz), marking higher efficiency.

2. Ability to deep carving

Laser deep engraving has the advantages of pollution-free, high precision, flexible engraving content, and can meet the complex engraving process. It can be used for engraving marks on industrial, machine and aerospace devices.

The laser used by Chuangxin Laser for deep engraving has large single pulse energy (>1.5mJ), strong deep engraving ability and higher efficiency; high power (>200W), deeper engraving depth; good beam quality, fine deep engraving shading .

3. Can be cleaned

Laser cleaning has a very wide range of applications in industry, including mold cleaning, equipment parts rust removal, high-speed rail rust removal, and gear decontamination.

The laser used by Chuangxin Laser for cleaning has large single pulse energy (>30mJ) and higher cleaning efficiency; high power (up to 500W), which can clean thicker rust layers; even spot energy distribution, cleaning does not damage the substrate.

4. Can cut

Laser precision cutting/punching is a major application field of pulsed fiber lasers, and it is also one of the important technologies for 3C processing and application. It can be used in mobile phones, notebook computers, PCB boards, earphones and other electronic products. Traditional computer gong processing technology, the surface of the material is easy to be convex, the hole edge burr problem, laser precision drilling can avoid this kind of problem.

Chuangxin laser precision cutting laser has good beam quality, less thermal effect in the cutting seam, no heat deposition, smooth cutting edges and no burrs; high peak power (>15kW), fast cutting speed, and flat cutting materials that are not easily deformed.

5. Can be welded

Pulsed fiber laser welding is mainly used for spot welding and seam welding of thin metal materials. By controlling parameters such as the waveform, width, peak power and repetition frequency of the laser pulse, a good connection between the workpieces can be formed. There are a large number of applications in industries such as batteries and electronic components.

Chuangxin laser precision welding laser has adjustable pulse width (1-350ns), which can adapt to welding of different metal materials; the pulse width is smaller, the frequency is wider, the welding is basically spatter-free and smoother, and the welding is firm.
