The laser, developed by China’s National University of Defence Technology, beams enough power to disable drones and cut through several materials from over 0.62 miles (1 km) away. ===================================================================== Chinese scientists have developed a portable 2-kilowatt (kW) fiber laser weapon that can operate in extreme temperatures. Reportedly capable of functioning in conditions between -58°F (-50°C) and 122°F (50°C), the new laser does not require cooling or heating systems. This breakthrough means the laser can be used anywhere on Earth, from the Arctic to the Sahara, without the need for bulky infrastructure. If true, the innovation is an impressive feat as...
