Chinese Scientists Show Off A Laser that Can Write Words in Mid-Air

Magic Pen

Researchers at Hongtuo Joint Laboratory in Wuhan, China, have designed what seems like a mysterious yet fascinating laser pen that can write in mid-air– an intriguing technique that could, theoretically, be an onramp to “Star Wars”– Esque hologram innovation.

The South China Morning Post reported the other day that the pen utilizes ultra-short laser pulses to strip the electrons from air particles and turn them right into light-emitting plasma with sufficient precision to create words in mid-air.

“With the new gadget, we can draw in the air without utilizing paper and ink”, lab lead researcher Cao Xiangdong informed the state-affiliated Science and Modern technology Daily this week, as reported by the SCMP.

The SCMP reported that the researchers stated they made use of 3D scanning to arrange pixels and create Chinese characters but did not entirely explain how the process works. Lengthy story short, it sounds fantastic. However, we are going to intend to see much more in the method of a demo.

Power User

The pen reportedly operates in incredibly small laser bursts, equivalent to just a few quadrillionths of one second. At the same time, its power output is roughly incomprehensible.

The laser pen could get to one million megawatts, according to the SCMP, which is not also far off from the overall quantity of power the United States can generate. Nevertheless, because the bursts are so short, the device does not draw an immense amount of power, making it– the scientists say– relatively safe to use.

The team is wishing the pen could someday be used in quantum computing, brain imaging, and other sophisticated technology. Or possibly we will even see some incredible brand-new holographic technology.
