Two-Color Laser Induced Electron Emission from Biased Metal Surface
By solving the time-dependent Schrödinger equation, we construct an exact analytical solution for nonlinear ultrafast electron emission from a dc-biased metal surface illuminated by two-color laser fields. Our results show a large dc bias can significantly increase the photoemission current, while maintaining a strong current modulation with respect to the phase delay of the two-color lasers. Application of our model to time-resolved photoelectron spectroscopy shows the dynamics of n-photon exited states depends strongly on the dc field.
