Scientists in China have developed a laser so powerful that it can be used to write in the air by using ultra-short pulses that strip electrons off air molecules and turn them into light. In other words, it essentially scars the air to create a floating ghostly-like image in mid-air. The team used it to create Chinese characters that could be viewed from any angle and even touch with their hands.
How does it work? Well, the system basically focuses high-intensity laser pulses in the air to create plasma, or ionized gas, which then emit energy in light form. A 3D scanner is then used to arrange the pixels and create characters in the air. Practical applications include high-precision manufacturing, medical instruments and quantum computing. Unfortunately (or fortunately), this isn’t quite yet powerful enough to achieve a laser-fusion record. uvBeast New V3 365nm Black Light UV Flashlight – HIGH Definition Ultraviolet - HIGH Power and Long Range Professional Grade Beam Best for Professional/Commercial Use – USA Stock No Standalone lithium batteries are sold with the product.

With the brand new device, we can draw in the air without using paper and ink. The display is an accumulation of our research over more than a decade”, said Cao in the report,” said Cao Xiangdong, lead scientist at the laboratory.
