SPI Lasers’ G3 30W Pulsed Laser offers several advantages in marking anodised aluminium. The lasers higher repetition rates can take advantage of higher scan speeds and can be up to 50% faster.

This is due to the reduced central intensity in the focal spot which results in less digging into the surface.
