It will change the original mode of traditional manual de-icing, reducing the risk of power workers risking to climb and rescue in bad weather. The reason why the “ice melting team” does not burn the lines is that these overhead lines have no insulation layer and are made of metal (steel core aluminum stranded wire), so they are not flammable. In addition, the laser pointer strictly controls the power and the quasi-head, and the drone Keep fire from a safe distance without hurting high-voltage lines.
Physicists are planning to build powerful lasers that can tear vacuum. In a narrow laboratory in Shanghai, China, physicist Li Ruxin and colleagues are creating the most powerful laser pulse ever, and thus breaking the world record. The laser developed by them is called “Shanghai Ultra-strong Ultra-short Laser Pointer Experimental Device”. The core of the device is a single cylinder with a width equal to that of a frisbee and composed of titanium-doped sapphire.
After lighting the light in the crystal and passing it through a system of lenses and mirrors, the light is turned into a powerful pulse that is shocking. In 2016, it reached an unprecedented 5.3 watts (English abbreviation PW, 1PW = 1000 trillion watts). The laser in Shanghai, China set a record for maximum power. At present, researchers are upgrading the laser with a view to breaking the record set by the end of this year, reaching 10 PW-equivalent to more than 1,000 times the power of the global grid.
