Two projects currently underway in Japan aim to use high-energy laser pointer for practical purposes. One of these projects is a government-funded innovation project initiated by the Japanese Cabinet in 2014. The project was led by Yuji Sano, the former chief engineer of Toshiba, through cooperation with Osaka University and the Japanese Institute of Physics and Chemistry…

Can be used for all kinds of lasers in the ultraviolet to near-infrared band
According to reports, researchers at Osaka University in Japan have developed a technique: By optimizing the virtual phase grating, the accuracy of laser pointer beam shaping and wavefront obtained by traditional methods can be improved without additional cost. The research results have been published in Scientific Reports. High-quality square flat-top beams have been widely used in various…
The U.S. is stepping up efforts to develop ultra-high energy lasers
According to reports, the USS Prebel guided-missile destroyer stationed in Pearl Harbor is about to become the first active warship in the US Navy equipped with high-energy laser pointer weapons. In May, the US Congress Research Service issued a report stating that the US Navy has made “substantial progress” in the shipboardization of laser weapons. Once shipborne…
Atmospheric laser pointer communication adaptive optics technology has made progress
The Key Laboratory of Adaptive Optics, Institute of Optoelectronics Technology, Chinese Academy of Sciences, has made new progress in the application of adaptive optics (AO) technology to space coherent laser pointer communication systems: high quality of 5Gbps under moderate atmospheric turbulence has been achieved in the laboratory The effect of spatial coherent laser communication. It is verified…
Does laser pointer technology solve the food crisis?
Russian scientists said that they have made new breakthroughs in agriculture and developed a laser pointer system that can double the growth rate of crops and does not require any pesticides in the cultivation process. This technology can be used in cities, or in remote areas, and it is said that it can greatly extend the storage…
Research and development of laser pointer manufacturing technology in the global market
The development prospects of laser processing. Laser processing used in remanufacturing is the same as it is used in other manufacturing industries. It has its irreplaceable advantages and is superior to other processing technologies. laser pointer processing for remanufacturing is developed from phase change hardening to laser surface alloying and laser cladding, and from laser alloy coating…
Talking about the application and development of laser processing technology
Laser processing refers to the use of the thermal effect of the laser pointer beam projected on the surface of the material to complete the processing process, including laser welding, laser cutting, surface modification, laser marking, laser drilling and micro processing. The laser beam is used to perform various processing on the material, such as drilling, cutting,…
Why do you need laser pointer headlights?
People cannot help asking: LED headlights already have the advantages of energy saving, long life, small size, low brightness attenuation, and corresponding fast speed. Why do we need laser pointer headlights? In fact, the laser light source is different from the ordinary light source, it is only a monochromatic light source, the light has only one wavelength,…
The display effect is related to the quality and brightness of the laser pointer light source
Lidar, also known as LIDAR (Laser Detection and Ranging), is a system that emits a laser pointer beam to detect the location, speed, and distance of a target. It is understood that lidar was originally used in the military field as a target detection and tracking system, and is considered to be a device that is more…
Nanophoton frequency converter can realize single photon color conversion
False-color scanning electron micrograph of a nanophotonic frequency converter containing a ring resonator (blue shaded part), and a waveguide (red part) is used to inject light into the ring resonator. The input signal is represented by a purple arrow and converted to a new frequency (blue arrow) by using two pump laser pointer (bright red and dark…
