Graduate Student Seminar - 09/16/2011

"Conical Terahertz Emission from Two-Color Laser-Produced Plasma"

by Yong Sing You

Friday, September 16, 2011 -- 12:00 p.m.
Large Conference Room, 1207 Energy Research Facility

Advisor:  Assistant Professor Ki-Yong Kim

Terahertz (THz) generation from two-color laser-produced plasma has attracted a considerable amount of interest nowadays due to its capability of producing broad bandwidth and high-power THz pulse. This talk will start with an introduction of THz science and technology with emphasis on THz sources. Later we will discuss a microscopic model to explain the THz emission from two-color laser-produced plasma. Our recent work on measuring THz profile and yield generated from this method will be presented. A simple model is developed to explain the role of plasma length, dephasing and optical group velocity in determining the THz profile.
