Femtosecond Lasers Used To Color Metals

Posted by kdawson on from the gold-ring-to-match-her-eyes dept.

Maximum Prophet writes "An optics professor and a postgrad have developed a way to use ultra-short pulses of laser light to etch nano features into the surface of metals so that they can absorb or reflect specific wavelengths of light. This is very similar to the way that butterflies get the color in their wings."

    Quick Poll:
