By laser

Laser marking machine can be divided into CO2 laser marking machine, semiconductor laser marking machine, YAG laser marking machine and optical fiber laser marking machine according to different lasers. According to the different laser visibility, it can be divided into: UV laser marking machine (invisible), green laser marking machine (visible laser), infrared laser marking machine (invisible laser).
By wavelength

According to the different wavelength of laser, it can be divided into: deep UV laser marking machine (266 nm), green laser marking machine (532 nm), light pump YAG laser marking machine (1064 nm), semiconductor side pump YAG laser marking machine, semiconductor end pump YAG laser marking machine (1064 nm), optical fiber laser marking machine (1064 nm), CO2 laser marking machine (10.64um).
