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…
The UK is developing a new laser pointer system to remove cancer cells
Experts at Heriot-Watt University in Edinburgh are developing a new system that will help surgeons better distinguish cancer cells from normal tissues and remove them without damaging the surrounding healthy tissue. The new system will be based on an ultrafast picosecond laser pointer, which provides energy in a pulse train of one trillionth of a second…
