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 most lasers of this power class require massive cooling units (like air conditioners in a shipping container) to avoid overheating or freezing. The device has been developed to cater to defense and industrial sectors.

“We have achieved a technological breakthrough in the performance of wide-temperature operating fibre lasers,” Chen Jinbao, vice-president of the National University of Defence Technology which led the development of the laser, explained in the paper published in the Chinese-language journal Higher Power Laser and Particle Beams in July.

The laser beams enough power to disable drones and cut through several kinds of materials from over 0.62 miles (1 km) away.
