Recently, researchers have developed a comb laser with higher stability and efficiency. The use of synthetic reflection self injection locking micro comb design enables the laser to achieve stability and increase conversion efficiency by more than 15 times. This efficient, stable, and easy to manufacture design is expected to make rapid progress in fields such as portable sensors, autonomous navig...
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...
Quantum photonics is one of the important research directions in the quantum field, which utilizes the unique properties of light at the quantum level. The core of this field is the deterministic single photon source, which sequentially emits individual photons through spontaneous emission and is the cornerstone of quantum communication, computing, and secure encryption. However, under environment...
Recently, the team led by Wang Rui from the Future Industry Research Center and the School of Engineering at Xihu University has made significant breakthroughs in the field of flexible stacked solar cells. They have successfully stacked perovskite and copper indium gallium selenide materials together, resulting in a photoelectric conversion efficiency of 23.4%. The related research paper was recen...
Petrobras announced last week that it plans to use laser beams to measure wind speed and direction. The idea is that these data will be used to improve the operation of the wind turbines maintained by this state-owned company in North Rio Grande do.The total investment of the 2.0 version of this device reaches R $11.3 million, known as the offshore wind assessment remote buoy.This technology can a...
