Plasmonic metamaterials have recently received increasing attention due to their favorable optical and electrical properties. The physics of the interaction between plasmonic metamaterials and lasers are rich and open opportunities for applications, such as sensing, imaging and photovoltaics. Here, we investigate the mechanism of the interaction between Ag nanorod arrays and nanosecond (ns) pulsed laser. The experimental results show that ns laser pulses significantly improve the crystallinity of the Ag nanorod arrays. Meanwhile, the laser evaporates some of the Ag into the air. This work paves the way for future high-performance plasmonic meta-devices.

等离子体银纳米棒阵列与纳秒脉冲激光之间的相互作用

等离子体等离子材料由于其良好的光学和电学性质，近来受到越来越多的关注。等离子超材料与激光之间相互作用的物理学为诸如传感，成像和光伏等应用提供了丰富而开放的机会。在这里，我们研究银纳米棒阵列和纳秒（ns）脉冲激光之间的相互作用的机制。实验结果表明，ns激光脉冲显着提高了Ag纳米棒阵列的结晶度。同时，激光将一些银蒸发到空气中。这项工作为将来的高性能等离子元设备铺平了道路。
