Title: ALS Seminar: Dr. David Cook, 'THz Systems Development: Instruments for research and specific applications'
When: 01/16/2013 10:00 AM - 10:45 AM
Description: Title: "THz Systems Development: Instruments for research and specific applications"
Speaker: David Cook, Ph.D.
Date: Wednesday, January 16, 2013
Time: 10:00 - 10:45 AM
Location: Building 71, 264 Conference Room
In order to develop commercial THz applications, general purpose THz instrumentation is required for characterizing material properties and proof-of-principal measurements. The design of a versatile time-domain THz apparatus will be discussed in context with the development of THz sensors for specific applications including portal security and industrial coating characterization.
David Cook received a BA from Grinnell College with a major in Chemistry and a Ph.D. in Chemistry from UC Berkeley. While working with Professor Richard Saykally, David investigated infrared fluorescence from UV laser excited polycyclic aromatic hydrocarbons in order to assess their relationship to the unidentified infrared emission bands. After receiving his Ph.D., David worked as a post-doctoral researcher with Professor Robin Hochstrasser at the University of Pennsylvania where he investigated nonlinear spectroscopic techniques utilizing ultrashort pulses of visible and THz radiation to probe dynamics in liquids. In the course of this research, David discovered a new four-wave optical rectification process for generation of intense broadband single cycle THz pulses in laser generated plasmas. David then moved on to developing industrial applications of THz technology at Physical Sciences Incorporated where he worked for eleven years. These applications include sensing of illicit substances such as explosives for portal security and measurement of industrial coatings for ships and aircraft for quality control purposes.
