Abstract

Optical constants of lactose pumped by strong terahertz (THz) waves have been investigated. The sample was measured by a THz-pump/THz-probe system, in which the electric field strength of the pump-THz waves exceeds 120 kV/cm. When the lactose sample is pumped by strong THz pulses, its probed response signal lasts about 2 ps. With different delay time, the optical constants of lactose was also measured and discussed. The experimental results show that the optical properties of lactose molecules can be changed by high-intensity THz waves, and this change is related to the applied the interaction time, which is in the order of picosecond.
