Professor Zhang Huaijin and Yu Haohai from the Institute of Crystal Materials of Shandong University (the State Key Laboratory of Crystal Materials) proposed a spatial harmonic modulation strategy, which realizes the phase matching conditions that can be manipulated artificially in the new quartz crystal, and realizes the effective frequency doubling within the VUV range. The relevant research is ...
Energy conversion technology is an important research direction in modern science and engineering. Scientists are exploring new catalytic chemical methods to achieve the conversion of energy chemicals, such as photocatalysis and electrocatalysis. However, these highly anticipated catalytic chemistry technologies still have some problems in practical applications, and there is still a certain dista...
Researchers at the University of St. Andrews in Scotland have manufactured the first organic semiconductor laser to operate without the need for a separate light source - which has proven to be extremely challenging. The new all electric driven laser is more compact than previous devices and operates in the visible light region of the electromagnetic spectrum. Therefore, its developers stated that...
Light can calculate functions during propagation and interaction with structured materials, with fast speed and low energy consumption. The use of all optical neural networks for general computing requires an optical activation layer with nonlinear dependence on the input. However, existing optical nonlinear materials either have slow speeds or very weak nonlinearity at the level of natural light ...
The energy transformation has brought us global challenges. In this regard, renewable energy sources such as photovoltaic are crucial. The key to improving the efficiency of photovoltaic power generation is to improve the manufacturing process of solar cells. Laser material processing is used to weld individual batteries into modules, dope selective emitters, and remove very thin antireflective an...
