飞秒Laser场致发射源及其发射机理

Site-Selective Field Emission Source by Femtosecond Laser Pulses and Its Emission Mechanism

Hirofumi Yanagisawa

摘要:

本文综述了近年来飞秒弱激光脉冲诱导的非对称场致发射及其发射机制的实验和理论研究。进一步讨论了更宽范围的直流电场和激光功率的发射机制。结果表明,首先,低激发阶的光助场发射在较高的直流电场中增长,其次,我们的模拟只能适用于较低的激光功率。

英文摘要:

Recent experimental and theoretical investigations on asymmetric field emission induced by weak femtosecond laser pulses and also its emission mechanisms are briefly reviewed. The emission mechanisms are discussed further for a wider range of DC fields and laser power. It appears that firstly photo-assisted field emission from lower-excitation order grows in the higher DC fields and secondly our simulations can be applied only for lower laser power.
