The technology is evolving in an impressive way. It has evolved so much that it has allowed Chinese researchers to invent a laser so powerful that it can be used to cut through air.
Si la ville de Wuhan, en Chineis well known for being the birthplace of Covid-19it is also in this city that a laser revolutionary capable of cut out the air. Designed by a team of researchers from the Hongtuo Joint Laboratory of Ultra-Fast Laser, this futuristic laser works by knocking electrons out of air molecules using ultra-short laser pulses. This allows them to be transformed into light. In a demonstration of the laser, the device was used to write Chinese characters in the air, a scene worthy of a work by science-fiction.
The researchers claim that the use of the device is much broader than what was shown during the demonstration. In particular, the laser makes it possible to draw any pattern in the air : « With the brand new device, we can draw in the air without using paper or ink “, indeed declared Cao Xiangdong, principal scientist of the study, with the South China Morning Post. While this is already an incredible feat, the scientists hope that their invention can be used in many fields, such as brain imaging or quantum computing.
The question that arises is: might this invention make it possible to create a real lightsaber?
