The new device is a frequency comb - a special type of laser that can generate multiple wavelengths of light, each with a fixed frequency interval. On the spectrogram, it looks a bit like the teeth of a comb. In approximately a quarter century since their first development, these "cursor rulers" have completely transformed various high-precision measurements from timing to molecular detection. In ...
According to the University of Cambridge, researchers have developed a new method for 3D printing metal, which can help reduce costs and more effectively utilize resources. This method, developed by a research team led by the University of Cambridge, allows structural modifications to be "programmed" into metal alloys during 3D printing - fine-tuning their performance without the need for thousand...
