Ultrafast Terahertz Spectroscopy

Dr. Michael Hasselbeck

Department of Physics and Astronomy, University of New Mexico, Albuquerque

Technological advances in the last decade have led to the realization of precisely triggered, very short bursts of electromagnetic radiation in the far-infrared region of the spectrum. This wavelength region, spanning roughly 1 mm to 30 microns, is situated between microwave and infrared frequencies. It has been traditionally difficult to access due to the lack of practical sources and detectors. In this informal talk, I will review some terahertz generation and detection schemes based on ultrashort optical laser systems. Ultrashort terahertz pulses have provided researchers with new perspectives in the spectroscopy of condensed matter and semiconductors in particular.
