The development time of LED light source projectors is also very long, especially because of its small size, high portability, and simple use. At present, the performance of LED light source projectors has reached the high-definition level. The mainstream LED light source projectors are mainly hundreds of lumens high-definition projectors, which have been recognized by…

From a theoretical point of view, a projector using a laser light source can achieve a color space much larger than that of a traditional light source, and its color performance is higher than that of a conventional light source. At the same time, the traditional projector will produce brightness attenuation, color saturation, contrast reduction…

German and American scientists have jointly created a laser with a spectral line width of only 10 millihertz (1 millihertz is 0.001 hertz), setting a new world record for laser monochromaticity. According to a press release issued by the German Federal Institute of Physics and Technology, this is the laser pointer closest to ideal monochromaticity so far….

Researchers from the German Federal Institute of Physics and Technology (PTB), the United Joint Astrophysics Laboratory (JILA), and the National Institute of Standards and Technology created two independent lasers, each with its own silicon Fabry-Perot Luo cavity, laser pointer line width is only 0.01Hz. This is a world record, much smaller than the usual linewidth of kilohertz…

The laser industry is changing rapidly, full of challenges and opportunities, and physicists with multidisciplinary training will be ideal candidates for this field. The company is located in Bozeman, Montana, USA, and mainly produces laser pointer and optical devices. We have been developing for decades since the laser was invented, but many aspects of the optoelectronics industry…

Because the current machine price is 25% of the price a few years ago. The new government plan also provides investment subsidies as well as interest subsidies and insurance. Sharma hopes to resume investment within a year, which is why Vibrotech sold more than 50 economical fiber laser cutting machines last year. In the 21st…

The laser interferometer gravitational wave observatory (LIGO) announced that the third detection of gravitational waves was not more than one month. Recently, the United States “Wired” magazine reported that several independent physicists had laser The laser pointer data raises questions. Danish physicist Andrew Jackson and four others jointly wrote to Quantum Magazine that after detailed analysis of…

The US Navy conducted a laser pointer weapon test in the Persian Gulf and struck a drone with precision. The laser weapon system, abbreviated as LaWS in English, is deployed on the US military amphibious carrier “Ponce”. The captain of the ship, Wells, said: “This system is more accurate than bullets. This is not a highly specialized…

The interacting laser circle is a new laser pointer model that can be used to explore topological defects and disordered structures in seemingly unrelated systems. If the molten iron is cooled slowly, the spins of the electrons can gradually be aligned in the same direction, thereby generating a strong magnetic field. However, rapid cooling of the molten…

Researchers at the Shanghai Institute of Applied Physics of the Chinese Academy of Sciences have recently proposed a new mechanism for generating high-brightness, fully coherent radiation based on storage ring light sources. Studies have shown that this operating mechanism can make full use of the characteristics of the storage ring electron beam, and can achieve…
