Source: China – South China Morning PostChinese researchers have manufactured the world’s largest barium gallium selenide (BGSe) crystal, a breakthrough that could pave the way for ultra-high-power laser weapons capable of zapping satellites from the ground.
The synthetic crystal, measuring 60 millimetres (2.3 inches) in diameter, efficiently converts short-wave infrared lasers into mid- to far-infrared beams that can penetrate atmospheric windows for long-distance transmission.
Crucially, it can withstand laser power as intense as…Read More
