In the context of the transformation of industrial manufacturing to high efficiency and energy saving, wavelength lock fiber technology has recently achieved large-scale mass production, and its high-power fiber laser has outstanding performance in thick plate cutting scenarios, increasing the cutting speed by 3-4 times compared with traditional equipment and reducing the operating cost per meter by about 80%. This technology achieves a stable output of 710W in a 20°C-30°C environment through the inclined multi-core and polarization beam process, compressing the fluctuation range of laser power from ±1.5% to ±0.5%, providing a reliable guarantee for high-precision machining.

The mass-produced 915nm and 976nm series optical fiber modules have an electro-optical conversion efficiency of more than 40%, of which 20kW products can reduce material losses in steel structures, shipbuilding and other fields compared with traditional plasma equipment, and a single 40kW equipment can save about 900,000 yuan in board costs per year. Up to now, related technologies have been applied to laser welding, 3D printing and other scenarios, and the sales of supporting 10,000-watt lasers have exceeded 23,000 units, becoming the core supporting device for industrial upgrading.
