METHODS AND SYSTEMS FOR THE ENHANCEMENT OF TERAHERTZ WAVE GENERATION FOR ANALYZING A REMOTELY-LOCATED OBJECT

摘要

A method for generating terahertz radiation includes inducing a background plasma in a volume of a gas by focusing a first optical beam in the volume, and generating pulsed terahertz radiation with enhanced generation efficiency by focusing a second time-delayed optical beam in the background plasma. The method may be implemented in a system for detecting and analyzing a remotely-located object.
