Foreign media reported that the US Navy plans to install high-energy lasers and integrated optical blind surveillance weapons (HELIOS) systems on the Arleigh Burke-class Flight IIA destroyers deployed on the west coast of the United States by 2021. It is understood that the HELIOS system can emit 60 kilowatts of laser pointer, which is three times…

A new method to control the launching direction of a miniature laser pointer
Researchers at Washington University in St. Louis have found a way to provide photons or light packets according to their instructions. The researchers used the generous energy state of a light domain to create photons in their laser pointer system so that they travel in a consistent pattern, clockwise or counterclockwise. For all laser systems and applications…
Laser pointer interference gravitational wave detector
Gravitational waves were directly detected for the first time after Einstein predicted the 100th anniversary of gravitational waves. The specific time is September 14, 2015. LIGO’s two probes in Louisiana and Washington state detected the merger of two black holes with 29 and 36 solar masses believed to be 1.3 billion years ago (GW150914 )….
How to ensure the accuracy of laser pointer measurement data?
With the development of science and technology, more and more industries need to use laser pointer diameter gauges, such as wire and cable, metal processing industry, rolling mills, laboratories, rubber industry, plastics industry and so on. The single-axis diameter gauge is a small desktop outer diameter testing equipment that can measure the outer diameter quickly, without damage,…
Circular beam semiconductor side emitting laser pointer
The semiconductor laser has been widely used since its birth in 1962, but it still has a much criticized shortcoming, that is, a large divergence angle and an elliptical light emission. Usually the vertical half-angle divergence angle is greater than 30°, and the horizontal direction is about 10°, which results in lower beam quality and…
The most efficient nanowire laser pointer in the world
Perovskite materials have the advantages of low cost, simple process and high efficiency, and are commonly used materials for solar panel research. Now, researchers have proved that nanowire laser pointer made from lead halide perovskites are the most efficient lasers known. Topological image of the nanowire (left insert). At room temperature, two different halide nanowire laser emission…
Data writing storage device based on ultrafast laser pointer
Modern life revolves around data, which means that we need new, fast, and energy-saving ways to read and write data on storage devices. With the development of magnetic material all-optical switching (AOS) technology, the optical method of using laser pointer pulses instead of magnets to write data has received considerable attention in the past decade. Although fast…
Blood turns into a laser pointer transmitter for drug testing and cancer treatment
It is reported that researchers from the University of Michigan in the United States have developed a new technology to monitor cell structure and molecular level activities by combining laser pointer with FDA-approved green fluorescent dyes. This work may one day improve clinical imaging and will better monitor tumors and other cell structures; and during drug testing,…
Interpretation of Femtosecond Laser Pointer Operation Characteristics
Femtoseconds can also be called femtoseconds, which is a unit of measurement for marking the length of time. Taking 1 second as a reference, 1 femtosecond is only one quadrillionth of a second. It can be seen that femtoseconds represent a very short time. Even if light can fly 300,000 kilometers per second in a…
Do you know the application of laser pointer welding technology in automobile manufacturing?
In the automobile manufacturing process, laser technology is mainly used for tailor welding of body plates with different thickness, body welding and auto parts welding. laser pointer welding is used in automobiles, which can reduce the weight of the car body and achieve the purpose of fuel saving; improve the assembly accuracy of the car body, increase…
