The development deals in CO2 RF Laser Tube, Basically Laser is an acronym for Light Amplification by the Stimulated Emission of Radiation. When light is referred to, it is based on a term called wavelength from the electromagnetic spectrum. There is visible light ranging from 380nm to 780nm, and for CO2 lasers there is infrared light ranging from 9,300nm to 10,600nm. By comparison, the popular fiber laser source operates at a wavelength of 1,064nm. It’s the wavelength of the laser light that determines which materials you can cut, mark, or engrave with your laser.
