Color laser engraving on titanium with 355 nm DPSS UV Endurance laser machine.
IN our experiment it is necessary to obtain different colors of engraving on titanium.
Used Endurance 3W 355nm laser with Galvo installed for engraving An RC 7110 scanner with a lens installed, having a focal length of 160 mm, a wavelength of 355 nm, a working area of 110 mm by 110 mm. The work was carried out on a titanium sheet with a polished surface.
1/3/5/12 watt UV 355 nm DPSS laser modules for engraving, marking and research
The engraving was carried out in the form of a square 7 mm by 7 mm. The height of the table was 10.5 cm. Color laser engraving is obtained by creating an oxide layer on a metal surface that refracts light.

With the Endurance 3 watt, 355 nm laser, you can engrave color engraving on titanium with colors: found, yellow, green, blue, brown, black and their various shades. It is possible to make color pictures on titanium. Color laser engraving is obtained by creating an oxide layer on a metal surface that refracts light. With portrait adjustment, you can change the thickness of the layer, thus changing the color of the picture. The titanium plate can contain different chemicals that can be used for the same settings.
