The test has two advantages. The first one is: In principle, it happens often, which is also certain. The second is that the photon is not lost, but just transferred, so it can be used for other purposes. This scheme uses a single fixed rubidium atom, which is cooled to near absolute zero by a laser…

Scientists look for laser pulses carrying this civilization signal around strange stars
According to media reports, scientists discovered a strange light curve on the KIC8462852 star, suggesting that there may be an alien civilization here. A huge structure appeared near the KIC8462852 star. To help rule out this possibility, scientists searched for all the signals around the star, one of which was a very short laser pointer pulse. If…

Ion beam detection laser pointer optical resonator
Researchers have discovered that the performance of micro-optical resonators can be finely measured and adjusted by ion beams. This discovery will help improve the production of holes used in sensing and quantum computing. Researchers from the National Institute of Standards and Technology use lithium ions with a radius of 50 nanometers to induce surface deformations…
Graphical process laser pointer in micro-nano processing
The patterning process of micro-nano processing is mainly divided into two technologies: pattern transfer and direct processing. The pattern transfer technology includes three parts: thin film deposition, pattern imaging, and pattern transfer. The direct processing laser pointer beam etching technology has the ability to write directly, avoiding the multi-step process of pattern transfer, by controlling the focused…
New laser pointer manufacturing process revolutionizes the photovoltaic market
The Solar Energy System Research Institute in Freiburg, Germany has developed a laser pointer-based manufacturing process method that is revolutionizing the photovoltaic market. Mass production of point-contact solar cells was realized for the first time. Millions of batteries with high efficiency levels have entered the market. In the next few decades, one of the main challenges…
Different types of lasers are built on silicon materials
Building a quantum cascade laser on silicon is extremely challenging, mainly due to the strong absorption of SiO2 in the long-wavelength mid-infrared band. “This means that we not only need to build different types of laser pointer on silicon materials, but also different types of silicon waveguides.” The project leader said: “We built SONOI waveguides and used…
