The core principle of a laser marking machine involves directing a focused laser beam onto various material surfaces. This light energy induces physical or chemical changes on the surface layer, resulting in the creation of permanent markings like patterns, trademarks, or text. Common types include CO2 laser marking machines, fiber...
Cooling Difficulties of Water-cooled Chillers Cause Analysis and Maintenance Guide
Industrial water chillers are categorized in various ways, one of which is based on the cooling method: water-cooled and air-cooled water chillers. Air-cooled water chillers are known for their simpler installation, while water-cooled water chillers are recognized for their larger cooling capacity and higher energy efficiency ratio. Water-cooled water chillers...
What is a Femtosecond Laser
A femtosecond laser is a special type of laser that emits extremely short pulses of light. These pulses are incredibly brief, lasting only a few femtoseconds (fs). To give you an idea of how short that is, one femtosecond is one quadrillionth of a second (10⁻¹⁵ seconds)! Because of these...
