Summary
Researchers discovered that peacock feathers contain tiny reflective structures capable of amplifying light into a laser beam. By dyeing the feathers and energizing them with an external light source, they observed the emission of narrow yellow-green laser beams. Published in Scientific Reports, this study marks the first example of a laser cavity in the animal kingdom.
