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 ...
The rapid development of intelligent cars and autonomous driving technology has made millimeter wave radar inconspicuous, and the widespread application of millimeter wave radar has driven the technological evolution of MMIC.From the expensive gallium arsenide (GaAs) process in the early days to the mainstream CMOS and SiGe processes today, and then to the future promising FD-SOI process, the cont...
Multi photon 3D laser printing technology, as a disruptive micro manufacturing technology, is facing two major challenges: speed and material compatibility. However, the latest research has made breakthrough progress, successfully increasing printing speed tenfold while maintaining excellent detail accuracy.In this remarkable study, scientists abandoned the traditional single beam printing method ...
Neptunium is the main radioactive component of nuclear waste, with a complex atomic structure that can be explored through mass spectrometry. This analysis is crucial for understanding its inherent characteristics and determining the isotopic composition of neptunium waste. Magdalena Kaja and her team from Johannes Gutenberg University in Mainz, Germany have developed a novel laser spectroscopy te...
Recently, Tong Cunzhu, the research team of the Chinese President of Science, Chunguang Institute of Mechanical Mechanics, made important progress in the research field of photonic crystal surface emitting lasers (PCSEL), proposed a three lattice structure and achieved a low threshold 1550nm PCSEL. Relevant achievements were published in Light: Science and Application vol.13, 442024, and the famou...
