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

Laser soldering is widely used in the manufacturing of automotive parts. Here are some common automotive parts that can be welded using laser soldering:Automotive electronic control systemEngine Control Unit (ECU): The engine control unit is the "brain" of the car engine, which receives signals from various sensors and controls the operation of the engine based on these signals. Laser soldering ca...

Researchers from Sichuan University, the Key Laboratory of Advanced Special Materials and Preparation Processing Technology of the Ministry of Education, and the Nuclear Additive Manufacturing Laboratory of China Nuclear Power Research and Design Institute reported on the study of the ultra capillary performance of laser powder bed melting additive manufacturing composite structure liquid absorbin...

Single pixel imaging (SPI) is a novel computational imaging technique that has been widely studied in recent years. This technology only uses single pixel detectors without spatial resolution to obtain spatial information of targets.It has unique advantages and compensates for the shortcomings of traditional imaging technologies based on array detectors, such as relatively immature or expensive ar...

The current deep neural network system (such as ChatGPT) can quickly improve energy efficiency by 100 times in training, and "future improvements will greatly increase by several orders of magnitude. Scientists from MIT and other institutions have demonstrated a new optical neural network training method that can crush state-of-the-art electronic microprocessors.Moreover, the computational density...
