A quite new carbon nanomodification used for the protection from laser damage

What is it about?

Lasers are getting more and more common, so also the risk for misuse is rising. Lasers are dangerous for eyes and sensors. A possibility to protect them is to produce optical limiting filters. They are able to attenuate the energy of a laser, by decreasing transparence above a certain energy threshold. There are several materials, which are able to induce this effect. Quite common are carbon nanomodifications like carbon nanotubes. This article shows the first example of the use of carbon nanohorns for optical limiting.
