When we think of a laser, the first image is that of weapons that trigger light bodies capable of crossing bodies and walls or science fiction sabers that cut the wind. But the reality is that a laser is a device that generates an intense and concentrated beam of light. Basically, A laser takes energy and makes it an extremely precise and powerful beam of light. And that could come from the most unsuspected sites.
A team of scientists has concluded that The tail feathers of the real turkeys can emit narrow beams of light. This is because the tail feathers include tiny reflective structures that can amplify the light and turn it into a laser beam.
In a study published in Nature, the authors, led by Nathan J. Dawson, explored these structures, which can emit a very different distinctive shine after applying a special dye to several areas of the tail of a real turkey. The results showed that The feathers can emit two different frequencies of laser light from multiple regions through their colored ocellos. Dawson’s team affirms that this is the first example of biololeser cavity in the animal kingdom.
After dyeing the feathers and energizing them with an external light source, they discovered that they emitted narrow laser beams of greenish yellow color. The study investigated the light emission properties of the barbulas (very fine filaments that branch from the beards of the bird feathers) infused with the tint of the tail feathers of the Indian peacock (turkey Christus) to High intensities pumped at 532 Nm (between 500 and 600 nanometers are green and yellow). Of course, the authors underline that several layers of dye were necessary before observing the laser emission.
“It was discovered that The ocular stain of a tail of a peacock dopada with dye emits laser light from multiple structural color regions. The regions where visible reflection bands were outside the dye’s gain region also emitted laser light at some points, ”says the study.
This finding could be an example of How complex biological structures can contribute to coherent light generation. However, the study does not identify the exact microstructures that generate laser emission.
A previous study claimed that the search for laser light in biomaterials could help identify regular microstructure sets inside. In medicine, for example, certain strange objects (perhaps viruses with distinctive geometric shapes) They could be classified and identified according to their ability to act as lasers.
