China’s domestically developed high-power picosecond laser has achieved commercial application in the field of ultra-hard material processing.
2025-12-16
China’s domestically developed high-power picosecond lasers have achieved a commercial breakthrough in the field of ultra-hard material processing, bringing about a technological revolution to the industry. Thanks to their ultra-narrow pulse widths and peak power levels, these lasers deliver “cold-processing” effects during machining, resulting in an extremely small heat-affected zone. This effectively prevents issues such as material deformation and microcracks that often arise from conventional laser processing, significantly enhancing machining accuracy and quality.
In the processing of ultra-hard materials, domestically produced high-power picosecond lasers have demonstrated remarkable adaptability. For example, the 100-watt ultraviolet picosecond laser launched by Beijing Shenglei Technology, built on a mature infrared picosecond technology platform, employs highly efficient harmonic conversion and active purification technologies to overcome the challenges of UV device damage and moisture sensitivity. This laser can be stably used for cutting hard and brittle materials such as carbon fiber, ceramics, and wafers. Meanwhile, Han’s Laser’s 200-watt infrared picosecond laser, with its integrated and compact design, achieves highly efficient processing in applications like lithium battery tab cutting and photovoltaic silicon wafer scribing. With cumulative sales exceeding 3,000 units, this laser has proven its commercial viability.
From a technical standpoint, domestically produced picosecond lasers have overcome the bottleneck of stable high-power output by leveraging self-developed seed sources, high-gain amplifiers, and pulse-selection technologies. Some companies have already achieved domestic substitution of core components, driving down costs and enhancing the autonomy and controllability of their supply chains. As industries such as semiconductors and new energy increasingly demand higher precision in processing ultra-hard materials, domestically developed high-power picosecond lasers are rapidly gaining traction in the high-end market and are becoming a key tool for upgrading manufacturing.
