Electrode sheet cleaning
Laser technology provides high-precision, noncontact surface treatment for battery-electrode manufacturing. The system efficiently cleans positive and negative electrodes without damage, removing dust, oxides and other contaminants to improve coating adhesion and battery consistency. A distinctive laser thinning process precisely removes micrometer-scale material from negative-electrode edges or selected regions, optimizing alignment and winding while avoiding the burrs, dust and damage associated with mechanical thinning. Consumable-free, environmentally friendly operation integrates easily into automated lines and improves battery safety and overall performance.

As a core precision optical component for wavelength screening, frequency locking and spectral demodulation, optical etalons are widely used in high-end scientific research and precision laser equipment.
As a vital emerging sector of modern three-dimensional spatial economy, the low-altitude economy has become a new global growth driver. It covers a wide range of commercial scenarios, including UAV navigation and obstacle avoidance, precise airspace management, aerial mapping, low-altitude logistics distribution, security monitoring and emergency disaster rescue. Nevertheless, frequent extreme weather, complex terrain obstacles and increasingly dense low-altitude flight activities pose severe challenges to the safety and stability of low-altitude aircraft operations.
Laser pump sources are the core energy input component of solid-state lasers and laser amplifiers, and their performance directly determines the output power, beam quality and service life of the entire laser system. In scenarios such as industrial processing, scientific research experiments and high-end equipment, improper pump source selection will not only result in substandard system performance, but also bring a series of problems such as rapid device degradation and high operation and maintenance costs. This article sorts out the core selection logic and key pitfalls of pump source procurement, and provides selection references based on mature, mass-produced high-reliability products to help purchasers efficiently screen suitable products.
