Plasmonic Meta-Surface for Efficient Ultra-Short Pulse Laser-Driven Particle Acceleration
摘要：
提出并分析了一种基于等离子体纳米天线的激光驱动粒子加速器。该概念利用纳米天线对电场的增强和定位来最大化加速度梯度并克服潜在的金属损失。该结构被优化用于使用在800 nm处工作的飞秒激光源加速相对论粒子，并且被示出为支持超短激光脉冲的带宽（高达16 fsec），同时提供可能达到11.6GV/m的高加速梯度。
英文摘要：
A laser-driven particle accelerator based on plasmonic nano-antennas is proposed and analyzed. The concept utilizes the enhancement and localization of the electric field by nano-antennas to maximize the acceleration gradient and to overcome potential metallic losses. The structure is optimized for accelerating relativistic particles using a femto-second laser source operating at 800nm, and is shown to support the bandwidth of ultra-short laser pulses (up to 16fsec) while providing a high acceleration gradient potentially reaching 11.6GV/m.
