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."

    .. but when I see things like "professor and a postgrad have developed", I assume that the postgrad did all the work and the professor took most of the credit.

    Quick Poll:

    Did the poster and/or editor intentionally make the ambiguous statement about butterflies, knowing that it would lead to a discussion 80% about laser-wielding butterflies, with real article-related content left to battle with the usual jokes/OT garbage/etc for the remaining 20% of comments?
