In laser processing, the focusing lens plays a crucial role. It concentrates kilowatts of laser energy into a micron-sized spot. However, the ZnSe material is notably soft. Furthermore, it easily attracts smoke and dust. Even tiny dust particles can quickly carbonize under high laser temperatures. This forms a "burn spot,"...
Laser Safety Classification Explained Risk and Distinction from Class 1 to Class 4
Lasers, these "miraculous lights," precisely treat diseases and process materials. However, they can instantly cause irreversible harm to humans. Thus, to quantify this risk, the International Electrotechnical Commission (IEC 60825-1) and the American National Standards Institute (ANSI Z136) established a universal safety classification system. Ultimately, therefore, understanding these classifications is...
RF Laser Power Drop Deep Dive into Eight Culprits and a Four-Step Troubleshooting Guide to Stop Profit Loss!
In daily laser processing, a laser power drop acts like a chronic equipment illness. It may not stop your machine immediately. However, it silently steals your profits through incomplete cuts and shallow markings. Therefore, for RF laser power decline, we must deeply analyze four key dimensions: optical, electrical, thermal, and...
