Key Parameters of Laser Source SystemIntroductionLaser systems are widely applied in cutting-edge fields including material processing, laser surgery and remote sensing. Regardless of diverse application scenarios, several core physical parameters usually determine the performance of the entire syst
Laser was first applied to cutting back in the 1970s. When a focused laser beam hits a workpiece, the irradiated area heats up sharply, causing the material to melt or vaporize. Once the beam penetrates the workpiece, the cutting process begins: the laser moves along the preset contour while melting the material. This is the basic principle of laser cutting.
As a professional solution provider for laser processing heads, we have long been deeply engaged in optical path adaptation and on-site process debugging for laser welding. We fully understand that on-site welding is frequently plagued by various defects such as porosity, cracks, spatter and incomplete penetration. These issues not only compromise the appearance and airtightness of products but also directly reduce weld strength, leading to batch rework and cost losses.
It’s not the appearance but the parameters that determine whether a laser is good or not. Laser sounds sci-fi, yet it has long been integrated into our daily lives: Metal cutting in factories, logo marking on the back of mobile phones, myopia surgery in hospitals, and data transmission via optical fiber broadband—all of these rely on lasers. So here comes the question: How exactly do we evaluate the performance of a laser? Today, we will break down the 7 most critical parameter indicators of a laser.
