Researchers Use Femtosecond Lasers To Display Touchable Images In The Air

 A Japanese company called Aerial Burton has been using lasers to ionize air molecules in midair for a few years now, thereby creating bright pixels that float in space. Using the original system, however, you were essentially creating floating plasma which could burn you if you touched it. Now, however, the company has reduced the power necessary to generate the images by using femtosecond… Read More
