China created a portable laser weapon the size of a suitcase: what is it capable of
For its part, a new Chinese laser can operate without protective heating or cooling systems at -50 ℃ to 50 ℃ and is close to the suitcase, writes South China Morning Post (SCMP). It is reported that the team under the leadership of the Vice President of the National University of Defense Technology China Chenbao has overcome the long -term task: stabilized the work of a laser for temperature drops of 100 degrees.
"We have reached a technological breakthrough in the productivity of fiber lasers operating in a wide range of temperature," the study said. The laser is based on an optical dual shell-99 percent of reflecting, at both ends cover alloy fibers alloy. When pumping it, itterbium is produced photons, reinforced in a deadly ray of 1080 nm, filtered and collced through quartz caps.
In laboratory tests, which simulate the transition from the extreme conditions of the Arctic to the conditions of the desert, the output power of the prototype was constantly exceeding 2 kW, reaching a peak of 2. 47 kW for 20 degrees, at efficiency 71 percent and almost ideal quality. It is critically important for this breakthrough - a rare earth element, more than two -thirds of the world's reserves that is controlled by China today.
Its unique quantum structure provides effective transformation of energy, while opposing thermal extinguishing. "Fiber lasers provide high efficiency, low cost and compact size, which allows them to be widely used in industrial processing, optoelectronic counteraction, precision cutting and other industries," scientists stressed. Recall that Coherent Aerospace & Defense is developing a next generation laser weapon for the US naval forces as part of the Sengbow classified program.
