Terahertz wave generation from thin metal films excited by asymmetrical optical fields

Abstract

We experimentally demonstrated terahertz (THz) wave emission from thin metal (gold) films excited by asymmetrical optical fields synthesized using an in-line phase compensator. By driving the electrons in thin metal films asymmetrically, THz wave emission is observed at normal incidence of two-color pump beams. Coherent control of THz wave emission from metal films suggests that a mechanism similar to that of the air-plasma THz source excited by two-color laser fields can be used to describe the generation processes.
