The working principle of the laser marking machine

Laser generation stage: The laser (such as an optical fiber laser) is excited by the pump source to activate the working substance. Under the magical effect of the resonant cavity, a high-energy laser beam is generated. This laser beam possesses extremely powerful characteristics such as high intensity, high monochromaticity, and high directionality! 

Beam Control Phase : The laser beam is transmitted through the optical fiber to the scanning mirror system. The control card acts like a smart little commander, precisely controlling the deflection of the mirror according to the computer instructions, guiding the laser beam to move along the preset path. Through the ingenious processing of the beam expanding lens and the focusing lens, a micron-level high energy density light spot is finally formed. It's simply amazing! 

Material Action Phase : The focused laser beam acts on the surface of the material, creating two super cool ways to form marks. One is thermal processing, where the laser energy causes the material to instantly melt or vaporize, creating indentations or color changes; the other is cold processing, where things like ultraviolet light can directly break the chemical bonds of the material, making it highly suitable for high-precision devices! And the entire process is non-contact, without generating mechanical stress. It's simply perfect!
