Traditional high-power lasers are mostly concentrated in the near-infrared spectrum. However, many critical materials have low absorption rates for infrared light, leading to significant thermal effects and limited yield rates during processing. While shifting to shorter wavelengths, such as green or UV, significantly improves processing precision, achieving stable, high-power output with high beam quality has long been a global technical challenge. Gongda Laser's recent success proves that domestic enterprises have mastered a series of independent core technologies-from nonlinear frequency conversion crystals and thermal management to resonator design. This effectively resolves the contradictions between efficiency, stability, and beam quality in high-power short-wavelength laser generation.
The creation of these two global records will have a profound impact on high-end manufacturing in China and worldwide:
Empowering New Energy and Electric Vehicles
The 4000W continuous green laser is the "perfect match" for highly reflective materials like copper and aluminum. Green light boasts an absorption rate 8 to 10 times higher than near-infrared lasers for these materials. This enables spatter-free, deep-penetration welding of core power battery components, significantly enhancing battery safety and production efficiency.
Driving Advanced Semiconductor Manufacturing
The 227W single-mode UV laser is hailed as a "cold processing" tool. Its extremely small heat-affected zone directly empowers cutting-edge micro-nano manufacturing processes that demand ultra-high precision, such as semiconductor wafer dicing, high-density PCB separation, and chip packaging.
Boosting Precision Additive Manufacturing
In 3D printing, high-power short-wavelength lasers enable smaller melt pools, higher precision, and superior surface quality. This opens up new pathways for printing precision components in the medical and aerospace industries.
