Flagship 500W Green Pulsed Fiber Laser —— Featuring 600μJ Single Pulse Energy at MHz-Level Repetition

As we enter 2025, global manufacturing is accelerating toward higher precision, efficiency, and intelligence. Laser technology is evolving rapidly and has become a key driver of advanced manufacturing in sectors such as new energy, consumer electronics, and the semiconductor industry. Among these innovations, high-power green pulsed fiber lasers are setting new benchmarks, offering excellent absorption at the 532nm wavelength for highly reflective materials such as copper and gold. With greater average output power, enhanced beam quality, and compact design, they are enabling breakthroughs in high-end, high-volume production and propelling the next wave of intelligent manufacturing.

Building on this momentum, GD Laser has unveiled a 500 W-level nanosecond green pulsed fiber laser, delivering single pulse energy up to 600μJ. Powered by self-developed high-precision optical components and a newly optimized frequency-doubling output head, the system achieves significant gains in performance and integration. The next-generation optical head module is 50% smaller and lighter than conventional designs, with dimensions comparable to mainstream near-infrared laser heads. It is fully compatible with existing near-infrared die cutting systems, enabling in-place upgrades.

Laser Output Power Measurement

Uncompromising Power & Stability
Through the optimization of the high-power fiber pumping structure and advanced thermal management, combined with the latest fundamental-frequency light amplification and frequency-doubling technologies, the system delivers 500W of average power output with exceptional power stability.

Note: Long-term test over 20h shows an excellent power stability with a standard deviation of less than 0.27%.

High Energy & High Consistency

In maximum pulse width mode, the single pulse energy can exceed 600 μJ. Even when the repetition rate is reduced to the minimum setting of 20 kHz, the system still delivers over 90% of the maximum single pulse energy achievable at typical operating frequencies. This ensures highly consistent cutting performance in high-speed die cutting applications requiring dynamic power and frequency adjustment.

Output Power and Single Pulse Energy Corresponding to Operating Frequency

Superior Beam Quality & Roundness

Leveraging an efficient high-order mode filtering design in the fundamental-frequency light source and an ultra-low-aberration external cavity frequency-doubling scheme, the system maintains a beam quality as low as 1.1 even under high-power operation. Meanwhile, spot roundness exceeds 95%, and the focused power density has been significantly enhanced compared to the previous generation, making it well-suited for applications that demand higher power density.

Streamlined Lithium Battery Manufacturing

Amid the surge in new energy development, higher standards for battery safety are being introduced, driving lithium battery manufacturing toward greater precision and efficiency.The 500W green pulsed fiber laser delivers over 600μJ of single pulse energy while reducing system volume by 50%. With stable absorption at short wavelengths, where copper absorbs approximately 40% at the 532nm green laser wavelength, it marks a major leap in usability and reliability. Fully compatible with existing infrared cutting systems, it offers a streamlined upgrade path for modernizing lithium battery production lines.  

Speed, Yield & Quality —— All in One Die Cutting

In the high-speed die cutting of cylindrical battery negative electrode sheets, traditional near- infrared pulsed lasers often struggle with both efficiency bottlenecks and inconsistent quality. Leveraging high energy output and precise control, GD Laser's 500W green pulsed fiber laser enables millions of high-speed cuts per second, delivering clean edges with virtually no burrs and a defect rate of less than 1 in 10,000. It significantly enhances the consistency and reliability of battery electrode manufacturing.

High-Precision Micro-Drilling of Copper Foil

Micro-drilling of copper foil is a critical process in lithium battery manufacturing, as the precision of these holes directly impacts battery performance and safety. GD Laser's 500W green pulsed laser, featuring exceptional beam quality and precise control, enables micro-drilling on copper foil with uniform aperture size and burr-free, smooth inner walls. This improves electrolyte wettability and enhances stability during charge/discharge cycles, providing a strong technical foundation for the R&D and production of high-performance lithium batteries.

Laminated Battery Cutting: Solving the Molten Bead Issue in HAZ

The cutting of laminated battery electrode sheets, particularly for negative electrode materials with short and long tabs, has long been a major challenge in the industry. Traditional infrared cutting processes often cause molten beads to form in the heat-affected zone (HAZ), resulting in poor edge quality and posing risks to battery safety, performance, and lifespan. GD Laser's 500W green pulsed laser prevents molten bead formation during cutting and produces negligible burrs, significantly improving cutting efficiency and product yield. This lays a solid foundation for the widespread adoption of laser-based solutions in the production and application of laminated batteries.
