CO2 series laser engraving machines employ the SYNRAD CO2 RF laser resonation and high-speed scanner head made in the U.S. provide reliable guarantee for long-time ,continuous, high-speed and stable operation of the machines.As a type of gas laser ,the CO2 RF laser operation at a laser wave length of 10.6um,namely ,at a medium infrared frequency band.The CO2 laser has high power and high electric/optical conversion rate.The laser employs CO2 as an operating material.CO2 and other suppporting gases are first charged into the discharge tube,high voltage is applied onto the electrode, then glow will generate in the discharge tube,discharge follows, and then gas molecules release laser.The released laser experiences beam expansion and agglomeration before deflection by the scanner for laser processing, The marking sofeware runs in the windows platform with chinese interface ,it is compatible with multiple types of software such as Autocad ,Coreldraw and Photoshop ,and with multiple file formats such as PLT,PCW,DXFand BMP.At the same time ,it can directly use SHX and TTF font libraries, The software is able to design figures at will through computer , with convenient operation ,The power is controlled by the software, continuous and adjustable.
