It is reported that Japanese startup EX Fusion will soon reach an agreement with Australian space contractor Electric Optical Systems to conduct on-site testing of technology for tracking small space debris orbiting Earth.Image source: LeolabsEX Fusion, headquartered in Osaka, specializes in the laser business with the goal of achieving commercial laser fusion reactors. So far, nuclear fusion rese...
Reducing stray light is one of the main challenges in combustion experiments using laser beams (such as Raman spectroscopy) for detection. By using a combination of ultrafast laser pulses and gated ICCD or emICCD cameras, a time filter can be effectively used to remove bright and constant flame backgrounds. When the signal reaches the detector, these cameras can open electronic shutters within the...
Recently, the team led by Academician Guo Guangcan from the University of Science and Technology of China has made significant progress in the field of integrated quantum storage. The research team led by Li Chuanfeng and Zhou Zongquan has improved the storage time of integrated quantum memory from 10 microseconds to milliseconds based on their original noiseless photon echo (NLPE) scheme, while s...
To make crystals suitable for use as optoelectronic materials, the key is to precisely control the crystallization, but this control is difficult.Producing lead halide perovskites, promising components for next-generation solar cells and photodetectors, has proven particularly challenging, with slow growth rates and uncontrolled nucleation being common issues.A project at Michigan State University...
With the rise of clean energy and the enhancement of environmental awareness, thin film solar cells are gradually replacing traditional silicon-based solar cells as an efficient energy conversion device.However, to achieve efficient solar cell conversion rates, the key is to ensure that thin film solar cells have clear edges and maximize light absorption. In this regard, the unique advantages of h...
