Russian scientists develop laser cannons
With the development of science and technology, many countries have to space launch a series of star detector, but because of not considering the probe after the completion of the work of recycling problem, now with a large amount of space junk floating in space, a fall in the process of transportation detector parts, there…
Femtosecond laser stimulation
Hu mingli of jing yi college of tianjin university and he he of Shanghai jiao tong university have proposed a new technology based on femtosecond laser pointer stimulation to directly activate the extracellular regulatory protein kinase (ERK) signaling pathway. This technology is like a “key”, which can directly activate cell signaling pathway and efficiently participate…
The trend of replacing traditional laser machining is clear
According to the latest research report of cicc, laser equipment has been growing rapidly due to its high processing accuracy, wide application range and rapid technological progress. From 2009 to 2017, the annual compound growth rate of global laser pointer processing equipment reached as high as 15. 9%, while the compound annual growth rate of…
Lidar is a new guarantee for intelligent security
With the rapid development of the security field in China, the security system is becoming more and more integrated, multi-functional and intelligent. The traditional single camera mode cannot fully meet the requirements of more and more complex, diversified and multi-functional security environment. The addition of lidar provides new solutions and new functional supplements for security…

Laser cladding is a new surface modification technique. It by adding in the base material surface cladding material, and make use of high energy density laser beam and fused together of base material surface layer method, at the grassroots level for metallurgical combination of surface and its cladding layer, which is the most important in…
Using lasers to measure changes in the earth’s ice
On Sept. 15, NASA launched the $1 billion icesat-2 satellite from vandenberg air force base in California, which will use a specially designed laser device to provide scientists with data on exactly where and how fast the ice is melting after it enters orbit 310 miles (499 kilometers) above earth. Weighing 341 pounds, icesat-2 is…
Advances in ultra-fast laser micro-nano manufacturing
Zhao quanzhong, vice President of nanjing advanced laser technology research institute, attended the summit and delivered the keynote speech of “progress and application of ultra-fast laser micro-nano manufacturing”. Ultrafastlaser pointer have unique ultrashort pulse, at a relatively low pulse energy to obtain the high peak intensity, thus can solve many conventional methods to meet the…
