Blue laser:The blue diode laser is a popular choice for beginners. It can engrave/cut wood, leather, paper, etch paint, but is less effective onwhite paint, certainblues, and clear acrylics. It has a 455nm wave length.
Infrared laser:Infrared lasers have a wavelength of around 1064 nanometers and are well suited to marking on certain types of metals such as gold, silver, copper, etc. Infrared lasers can be added to Blue laser machines by changing modules.(Atomstack R30 V2 laser module, Atomstack M4 marking laser machine)
Fiber laser:Fiber lasers are effective at marking metals at high speeds. As a rule, the larger the working area on a fiber laser, the greater the cost. Fiber lasers can be added to Blue laser machines by changing modules.(Atomstack MR20 laser module,IKIER 1064 nm laser module,IKIER K1 PRO 1064 nm)
