表面等离子体激元振荡电磁场存在下金属电子辐射的自发发射

Spontaneous emission of radiation by metallic electrons in the presence of electromagnetic fields of surface plasmon oscillations

Sandor Varro, Norbert Kroo, Gyozo Farkas, Peter Dombi

摘要:

解析地研究了金属电子在强增强表面等离子体场中的辐射自发发射。电子被描述为精确的修饰量子态,它包含了与等离子体场的非微扰相互作用。已经发现相当大的偏差从微扰行为的强度依赖性的发射的基波和二次谐波信号,即使在温和的入射激光强度。从形式主义推导出的理论预测与实验结果定性一致。

英文摘要:

The spontaneous emission of radiation of metallic electrons embedded in a high-intensity enhanced surface plasmon field is considered analytically. The electrons are described by exact dressed quantum states which contain the interaction with the plasmon field non-perturbatively. Considerable deviations from the pertubative behaviour have been found in the intensity dependence of the emitted fundamental and the second harmonic signals, even at moderate incoming laser intensities. The theoretical predictions deduced from the formalism are in good qualitative agreement with the experimental results.
