The transmission of electromagnetic waves (such as lasers) in plasma is a fundamental issue in plasma physics. In general, electromagnetic waves cannot be transmitted in high-density plasma, but their transmission and energy transfer play a crucial role in applications such as fast ignition laser fusion, laser particle acceleration, and ultra short and ultra bright radiation sources.In 1996, S. fr...
Recently, foreign researchers have made remarkable breakthroughs in the field of flexible energy storage devices, successfully developing a small energy storage device that can stretch, twist, fold, and wrinkle freely. This significant achievement has been published in the journal npj Flexible Electronics.With the booming development of wearable technology, the demand for energy storage solutions ...
Researchers printed microscale lenses directly onto optical fibers, allowing them to tightly combine the fibers and laser crystals into a single laser oscillator.Scientists have used 3D printing polymers in new micro optical technology, which can reduce the size of lasers and be used in various new applications, including the laser radar system for autonomous vehicle technology and cancer treatmen...
