超强激光脉冲实现单次全结构测量

Core Insights - A groundbreaking technology has been developed by the University of Oxford in collaboration with the Technical University of Munich and the Max Planck Institute for Quantum Optics, enabling the single-shot measurement of the entire structure of ultra-strong laser pulses [1][2] - This technology, known as RAVEN (Real-time Acquisition of Vector Electromagnetic Near-field), is expected to revolutionize the understanding of light-matter interactions and has significant implications for fields such as new physics and fusion energy [1][2] Group 1 - The RAVEN technology allows for high-precision measurement of the complete shape, temporal structure, and alignment of a single laser pulse, capturing its polarization state and internal complex structure [1] - This achievement provides unprecedented insights into laser-matter interactions and enables the optimization of high-power laser systems, overcoming previous technological limitations [1][2] Group 2 - The technology has been successfully tested on the ATLAS-3000 petawatt laser system in Germany, where the research team observed previously unmeasurable small distortions and wavefront shifts in real-time [2] - These space-time coupling effects significantly impact the stability and precision of ultra-strong laser experiments, and the RAVEN technology allows for precise calibration of the laser [2] - Furthermore, RAVEN offers a potential new pathway for inertial fusion energy devices, as the precision of laser focusing is critical in fusion experiments where ultra-strong laser pulses are used to heat plasma and ignite fusion fuel [2]
