Dyson V15 Detect: Saturn's low-cost laser cordless vacuum cleaner

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...

Researchers at the University of Rochester have created new micro comb lasers that go beyond previous limitations and have simple designs suitable for various applications. The research results are published in Nature Communications.Optical frequency combs are optical measurement instruments that have revolutionized atomic clocks, spectroscopy, metrology, and other fields. However, the difficulty ...

In the process of selecting electric vehicles, the effectiveness of the heating system is often overlooked. However, this system is crucial for providing a warm and comfortable driving environment and removing frost and fog from winter windows. More importantly, it can also improve battery efficiency, as the battery performs best within a specific temperature range.Unlike internal combustion engin...

Dr. Yongcui Mi from Western University in Sweden has developed a new technology that enables real-time laser beam shaping and control for laser welding and directional energy deposition using laser and metal wire. This innovative technology draws on the mirror technology used in advanced astronomical telescopes.Adaptive beam shaping using deformable mirror technology (Image source: Western Univer...

Semiconductor laser pump sources, especially those with a wavelength of 969nm, have become the preferred choice for high-power/high peak energy disc lasers due to their reduced quantum losses and heat generation.The 3000W 969nm fiber coupled semiconductor laser system launched by BWT uses 800 μ m NA0.22 fiber to output flat top optical energy distribution, combining lightweight and excellent optic...
