(1) Laser welding of alloy-strengthened metals can easily form low-melting eutectic due to solidified crystals, such as high-strength aluminum alloys; (2) The dynamic instability of the small holes in the laser pointer welding process is likely to cause the weld pores; (3) The size of the laser spot is small, which requires high assembly accuracy of the…

The object of future laser pointer welding technology application
At present, the United States, Europe and other developed countries have issued national plans in the field of military manufacturing to promote the research and application of advanced laser pointer welding technology. European Airbus is the first aerospace manufacturing company to use laser welding structure instead of traditional riveting structure for the connection of aircraft aluminum alloy…
Application and development of high-power laser pointer welding technology
Welding is the most widely used and most important method for permanent connection of materials. It has unique advantages in improving material utilization, reducing structural weight, and reducing costs. laser pointer welding is the fastest-growing welding method in the past ten years. It uses a focusable and adjustable high-energy density laser beam as a heat source to…
Air Defense Missile Laser Pointer Technology Applied to Civil Security Field
The first trick: civilian missiles! This is the “Skynet One” low-altitude defense interception system, which was put into use as early as 2011, with good results. The laser pointer system consists of fixed launchers and missiles, and mobile launchers can also be used. Its shape is quite similar to that of ordinary quadruple air defense missiles. Its…
China’s mysterious laser pointer weapon specializes in small drones
In recent years, Japan and other countries have successively exposed the accidental fall of small drones into the core area. Many of them laser pointer only knew what happened when the wreckage of the drone was discovered after the crash. Small aircraft, small in size, low altitude and low speed, and even silent approaching, no matter what…
Turkey develops two continuous wave anti-drone laser pointer weapons
According to reports, the Turkish Communication Security Research Center has completed the development and testing of two laser pointer systems and plans to equip the Turkish Army. It is understood that both laser systems use continuous wave lasers with an operating wavelength of 1070 nanometers (±10 nanometers). The first laser system is called Armol Vehicle Laser System…
In 2021 will be equipped with high-energy laser pointer weapons against drones
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…
New functional device based on laser pointer
One of the exciting things about this research is that it proposes an on-demand controlled laser. By changing the position of the scatterer, you can change the working system of the laser pointer. This will open up the possibility of new functional devices based on lasers. This research further enhances our ability to use micro-ring lasers….
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…
Human Cosmic Hearing Aid Laser Pointer
However, the space-time distortion caused by gravitational waves is very small. For example, when GW150914 reaches the earth, the strain is only 10-21. LIGO is an L-shaped modified Michelson interferometer, and its structure is shown in Figure 1. Two 4 km long interference arms are perpendicular to each other, and the arm length change produced…
