Chinese scientists unveil high-powered laser that can ‘write’ in the air

- The device uses extremely short, powerful bursts to turn molecules into light and can create any pattern desired
- The team, based in a lab in Wuhan, hope that one day their device can be used in fields such as precision manufacturing or brain imaging

Chinese scientists have shown off a laser that can create ghostly Chinese characters out of thin air.



Lasers have already been used to create a range of optical illusions, but previously they needed dust or clouds as a medium.

But the researchers behind the new device say it can draw patterns anywhere by using ultra-short laser pulses to strip the electrons off air molecules and turn them into light, creating a ghostly image floating in mid air.

In one demonstration earlier this week at the Hongtuo Joint Laboratory of Ultra-Fast Laser in Wuhan’s optics valley, researchers created characters that were visible from any angle and which researchers could “touch” with their hands.

“With the brand new device, we can draw in the air without using paper and ink”, Cao Xiangdong, lead scientist at the laboratory, told Science and Technology Daily in an interview published on Tuesday.

The device works by focusing high-intensity laser pulses in the air to create plasma, or ionised gas, which emits energy in light form.

The team said they had used a 3D scanner to arrange the pixel dots and form the characters precisely in the air, but did not explain how this works.

The short pulses last just femtoseconds – a time unit equivalent to one quadrillionth, or one millionth of one billionth, of a second.



Due to the extremely short duration of the pulses, the power peaks of Cao’s laser pen can reach a million megawatts, not far off the total utility-scale electricity generating capacity of the United States.

However, the average input power of the device is only a few tens of watts, which means it could be safely used in everyday settings.

“The display is an accumulation of our research over more than a decade”, said Cao in the report.

To “light” the air, lasers need to reach an energy density of 100 terawatts (a trillion watt) per square centimetre.

This presents a challenge to many other laser emitters of the same type but the researchers believe the technology has room for improvement, and more precise control of distribution of the laser pulse will allow them to create brighter, larger full-colour images in the air.

Cao’s team hopes that the technology will one day have a practical use in fields such as high-precision manufacturing, brain imaging, medical instruments and quantum computing.

Last year, another femtosecond laser based device produced by the lab, a disinfection machine, was validated by Wuhan University’s National Laboratory of Viruses for use in killing viruses and bacteria, including the coronavirus.

Am guessing either GM lying
"The U.S. Army has bought one Hummer through GM Defense," said Sonia Taylor, GM Defense spokeswoman. She wouldn't reveal how much the Army paid but said the Hummer retails for approximately $108,700.
108K? must have used CCP China China China sourced batteries in contravention to Congressional dictates, for the photo type.

Aha, here is the tell
Even though GM Defense recently rolled out a prototype eLRV, or electric Light Reconnaissance Vehicle, the Army appears to be receiving the civilian model (for now).

I wonder how many lbs of rare earth the beast requires in its motors?

US Army Embraces "EV Future" With New Electric Hummer

On Earth Day (Apr. 22), President Biden stated, "every vehicle in the United States military is going to be climate-friendly." He said, "we're spending billions of dollars to do it."
Months later, the U.S. Army bought a 2022 Hummer EV pickup from General Motors' subsidiary GM Defense, Detroit Free Press reported.



"The U.S. Army has bought one Hummer through GM Defense," said Sonia Taylor, GM Defense spokeswoman. She wouldn't reveal how much the Army paid but said the Hummer retails for approximately $108,700.

Taylor said that selling the Hummer is a 'stepping stone' to getting the service electrified. She added:
"We are trying to help defense and government partners transition to an E.V. future, so this is one of the steps.
"Our industry moves real slow. Slower than the commercial market. But this is a positive step in that direction."
The Army will receive the Hummer "no later than Aug. 31," Taylor said, adding she doesn't know what vehicle testing the service will conduct and where.

Detroit Free Press points out the Army's purchase description summarized in its bid:
"The purpose of this requirement is to procure a new light to heavy duty Battery Electric Vehicle (BEV) or series-hybrid electric wheeled vehicle, for Government analysis and demonstration."
Even though GM Defense recently rolled out a prototype eLRV, or electric Light Reconnaissance Vehicle, the Army appears to be receiving the civilian model (for now).



Biden's future "climate-friendly" military could be fraught with sacrifices, including diminishing warfighting capabilities, considering battlefields don't have convenient charging stations. It's possible EVs could be used in nontactical fleets.

The Army's going to have fun testing the new Hummer EV. It has more than 1,000 horsepower, and 11,500 pound-feet of wheel torque, allowing it to achieve 0-60 mph in 3 seconds.

UK and Australia seem more relaxed about CCP China China China once considering the practicalities of spending wallet contend, and dispenses with bothersome 'local' / 'friend' produced systems for its respective military and just source certain items completely assembled from China

The British Army wants to make all their troops specialize. They have also formulated a plan for the so-called future fighters and portable mobility. The procurement of these electric off-road vehicles from China is an initial exploration of the plan.

After testing the Chinese electric car, the British army is full of praise for its science fiction performance: no wonder Australia bought it



According to the latest report from local British media on April 25, although the size of the British army is currently shrinking, 10 Downing Street is still using its own army to save money. The biggest victim is the British Army. Originally, the British Army was only a small army unit with about 92,000 people. However, the latest disarmament bill issued by the United Kingdom not long ago called for another 12,000 reduction. In the future, the British Army will only retain about 80,000 people. In addition, the British even want to cut down all the army's tanks and armored vehicles, including the Challenger 2 main battle tank and samurai infantry fighting vehicles. In this way, the future British Army will completely become a lightly armed force.



??The historical trend of the British Army's abolition of main battle tanks and infantry fighting vehicles is inevitable. Under such circumstances, they have begun to prepare to purchase electric vehicles in order to maintain their mobility. On April 25, local time, the official account of Bowington Armored Test and Development Department in the United Kingdom released several photos of new vehicles being tested. A Polaris DAGORA1 off-road vehicle appeared on the screen, but the most fascinating The focus is on the two electric off-road vehicles on this off-road vehicle. These two electric off-road vehicles are produced by Hangzhou Qiulong Technology Co., Ltd. in my country.



One of the vehicles is the horned green bee electric off-road bike, and the other is the storm bee electric off-road motorcycle. According to the British Army’s own doctrine, they are preparing for the future form of combat. According to their ideas, the British Army will not continue to participate in large-scale ground battles on the European continent in the future, and this main task will be completed by the US Army. The British Army wants to make all their troops specialize. They have also formulated a plan for the so-called future fighters and portable mobility. The procurement of these electric off-road vehicles from China is an initial exploration of the plan.



It is worth mentioning that, according to the British Army’s combat concept, in the future, their basic combat unit will not be a division, but a brigade-level combat team. This brigade-level combat team will not be equipped with any tanks and armored vehicles. It places great emphasis on mobility and survivability, so this electric off-road vehicle is undoubtedly the best choice for them. It is also worth mentioning that Hangzhou Qiulong Technology Co., Ltd. has many similar products, and a series of weapons and equipment can be added to these vehicles, such as javelin anti-tank missiles and 12.7 mm large-caliber machine guns.



According to sources, after testing these Chinese-produced electric off-road vehicles, officers from the British Army were full of praise for the performance of their sci-fi. It is no wonder that Australia bought these equipment a few years ago, and they believe it. The equipment has greatly improved the combat effectiveness of the Australian Army. In the future, the British equipped with these vehicles will also make the British Army more portable and flexible to meet the needs of future warfare.
