Blue Laser (450nm)
The Conventional laser wavelength is Near-Infrared light, 800nm~980nm, the blue laser has a shorter wavelength of ~450nm. Yheabsorption rate of the light gives a metallic luster like, gold9Au) or copper(Cu) which, is higher than the conventional type. Therefore, laser processing with a low output is possible.
The Laser processing is done efficiently by low output, the reflective light of the laser bean becomes less. As a result, it reduces the damage caused by the laser reflection.
