Pulsed nanosecond laser is one of the main products. This series has a very wide product line, with power ranging from tens of watts to 2500 watts, and peak power from KW to MW. The largest application market for nanosecond laser pointer is the cutting of battery tabs, whether it is power batteries, 3C soft pack batteries, disc batteries, etc. At present, almost all lasers in these markets are processing. In addition, nanosecond lasers have applications in battery cracking, foil punching, thin-film solar cell etching, glass cleaning, and pole piece cleaning.
The application of fiber laser in 3C electronics industry. In addition, the YLPN pulsed nanosecond laser can achieve contrast color marking on ABS plastic, and the marking effect is good, and both machine recognition and naked eye recognition meet the requirements. The effect of nanosecond marking is similar to that of UV marking, but the efficiency, lifetime and cost performance are greater than that of UV laser. The ultrashort pulse laser belongs to the all-fiber series product, the overall volume is very compact, the laser head is 1.5 kg, which is very easy to integrate.
In terms of cost and price, ultrafast lasers are much cheaper than solid-state lasers pumped by semiconductor lasers, and the price/performance ratio is very high. Regardless of whether it is a picosecond or femtosecond ultrafast laser, the biggest advantage is that it can ensure the stability of single pulse energy within the repetition frequency range, and has a wider process window for debugging and experiments, which has a great advantage in improving processing efficiency.
The picosecond laser can be used for black marking of aluminum and stainless steel. This kind of black marking is mainly used in consumer electronics, medical equipment and daily necessities. The marking has high contrast, is permanently colorfast and more corrosion-resistant. Compared with the commonly used MOPA green laser pointer in the past, picosecond lasers are very advantageous in price, and the process window is wider than using MOPA, the fineness will be higher, and it will not yellow. In addition, picosecond lasers have applications in ceramic and glass marking, cutting high-brightness LEDs, thin film scribing and engraving in the solar industry, micro-machining and engraving of precision features, and cutting of thin metal foils.
Currently there is only a femtosecond laser called YLPF-10-500-10. The maximum pulse energy of this laser is 10μJ, the standard average power is 10W, the peak power can reach 20MW, and the pulse width can reach 100fs. Applications focus on: surface micro-texturing, foil cutting, sapphire deep carving, glass and plastic welding, etc. The green laser production line is also very rich, and the application is also very wide. It can be used for chip cutting, 3C glass cutting, PCB circuit board cutting, FPC cutting, high-strength carbon and glass fiber drilling, silicon nitride drilling and so on.
