We present a method of rendering aerial and volumetric graphics using femtosecond lasers. A high-intensity laser excites physical matter to emit light at an arbitrary 3D position. Popular applications can then be explored especially since plasma induced by a femtosecond laser is safer than that generated by a nanosecond laser. There are two methods of rendering graphics with a femtosecond laser in air: producing holograms using spatial light modulation technology, and scanning a laser beam using a galvano mirror. The holograms and workspace of the system proposed here occupy a volume of up to one cubic centimeter; however, this size is scalable depending on the optical devices and their setup.
