Lawrence Livermore National Laboratory develops PW grade thulium laser in the United States

The well-known journal Optica published a paper in November 2024 titled "Near complete extraction of maximum stored energy from large core fibers using coherent pulse stacking amplification of femtosecond pulses"The authors of the paper were the University of Michigan, Lawrence Berkeley National Laboratory, Peking University, and the German Institute of Synchrotron Radiation.The specific technique...

According to relevant media reports, a research team from the Helmholtz Center in Berlin, Germany, and Humboldt University has jointly developed a new type of perovskite stacked battery. This battery has broken the world record for similar batteries with a photoelectric conversion efficiency of 24.6%. In the solar cell family, in addition to silicon-based solar cells, there are also thin-film so...

TNO wrote that this is the first time Dutch technology has been used to send data from a satellite to a ground station press release on Earth. This technology uses invisible laser signals to achieve faster and safer data flow compared to ubiquitous communication radio frequencies.Kees Buijsrogge, Director of TNO Space, said, "This critical milestone marks a significant achievement for the Netherla...

Professor Zhang Huaijin and Yu Haohai from the Institute of Crystal Materials of Shandong University (the State Key Laboratory of Crystal Materials) proposed a spatial harmonic modulation strategy, which realizes the phase matching conditions that can be manipulated artificially in the new quartz crystal, and realizes the effective frequency doubling within the VUV range. The relevant research is ...

In recent years, the secondary battery equipment sector in South Korea has been hit by a wave of disruption, with demand temporarily stagnant and stock prices struggling to gain support. Especially for Youil Energy Tech, a manufacturer of secondary battery equipment, as the company is a latecomer to the laser equipment market, its sales cost burden is relatively high. It is expected that in the fu...
