Wuhan Optics Valley "Shangxin" black technology, femlose laser "light up" air generation can touch 3D image

The Yangtze River Daily Da Wuhan Client August 8th (Reporter Tan Fang) Can the air be lit? Recently, in the Hongtuo Super fast laser joint laboratory of Donghu High -tech Zone, R & D personnel used the original laser to "break through" the air. Chinese characters and graphics such as "Yangtze River Daily", "Horseshoe Lotus", "Flowers" were subsequently in the air. The middle floating is presented, and you can touch it with your hands.

This is a strange scene is the latest achievement of the Cao Xiangdong team of Hongtuo Chaotuo Laser Joint Laboratory. The high -energy and peak power femtosecond laser developed by the team can convert 2 watts of power into a million MW level and realize real 3D images in the air.

"2 watts are a small power, and nothing can be done, but 2 watts of femtosecond (one hundred trillion in 1 second) is incredible." The energy density of Taiwa per square centimeter, that is, the femlose laser on the size of the nail head, reaches 100 Taiwa energy output, and releases the ionizing air at the time scale of the femtosecond. The newly developed femtosecond laser can convert small energy into large energy, gather the "fastest light", and "light up" the air.

The 3D image formed by this new technology is different from traditional 3D display technology, which is expected to bring new changes to the display field. Cao Xiangdong introduced that at present, most 3D display technology uses the "pseudo -3D image" on the screen by using the visual differences between the eyes and the virtual synthesis of the human brain. And this flying laser uses three -dimensional physical space to renders the shape, glow or reflect light through laser to allow each virin (pixels in the corresponding plane) to arrange imaging in three -dimensional space. This also means that viewers can see 3D images at all angles and no dead angles.

"Air is the only medium it needs." Cao Xiangdong introduced that the advantages of this flying laser display technology are also reflected that it does not require any screens, no water fog and other media. High -altitude imaging is fine.

Cao Xiangdong introduced that at present, this femlose laser for air imaging has met the commercial requirements, and has reached the world's leading level in various indicators such as performance, cost, and volume. All key technologies have achieved localization. In the future, the team will further edit and control the time and space distribution of feet -laser pulse, and accurately regulate the characteristic parameters of the brightness, color and duration of the virus to further upgrade the power of the Femanto laser and achieve the real 3D display in the ultra -large air. "For example," for example It can be achieved on a one -kilometer -long screen display on the Yangtze River. "
