Bremen physicists enable energy-efficient nanolaser
human hair and works even at room temperature with no need of expensive cooling. The physicists Christopher Gies, Professor Frank Jahnke and Frederik Lohof from the University of Bremen’s Institute for [...] – so-called lasing – in the first place. “A normal laser is subject to huge losses,” explains Christopher Gies. “In fact, only 0.0001 percent of the generated light actually ends up in laser mode. The [...] mechanical features of the smallest lasers. With their computer-generated microscopic models, Christopher Gies, Frank Jahnke and Frederik Lohof were able to predict the behavior of the nano-system with
