We will have a talk from Prof.Donna Strickland on the 13th November from 4pm to 5pm. Refreshments will be served from 3.30pm. Details are below.
Long Wavelength Mid-Infrared using Two-Colour Fiber Laser Systems
With the help of nonlinear optics, coherent radiation is produced across the electromagnetic spectrum from X-rays to THz frequencies. However the mid-infrared radiation region, from 5 to 20 µm, known to molecular spectroscopists as the “fingerprint region” still has very few coherent sources, especially at the longer wavelengths. Short pulse systems at these wavelengths are even rarer. Two-color Chirped Pulse Amplification (CPA) laser systems can deliver two intense pulses needed to generate mid-infrared through the nonlinear process of difference frequency mixing. She will describe a two-colour Yb:fiber laser system that we are developing for Long Wavelength Mid-Infrared generation.
Prof. Donna Strickland received her B. Eng. Degree in Engineering Physics, from McMaster University in 1981. She graduated from the University of Rochester in 1989 with a Ph.D. in Optics. Along with her PhD supervisor, Dr. Gerard Mourou, Donna Strickland co-invented Chirped Pulse Amplification (CPA), which made it possible to amplify ultra-short pulses to unprecedented levels. From 1988 to 1991, Dr. Strickland was a research associate at the National Research Council of Canada. The following year, she was a physicist with the laser division of Lawrence Livermore National Laboratory. In 1992, she became a member of the technical staff of Princeton’s Advanced Technology Center for Photonics and Opto-electronic Materials. Dr. Strickland joined the physics department of the University of Waterloo as an assistant professor in 1997. At Waterloo, Dr. Strickland’s ultrafast laser group develops high-intensity laser systems for nonlinear optics investigations. She was promoted to Associate Professor in 2002 and since 2007 has been the Associate Chair of the Department. Dr. Strickland was selected as an Alfred P. Sloan Research Fellow in 1998. She received a Premier’s Research Excellence Award in1999 and a Cottrell Scholars Award from Research Corporation in 2000. She is an OSA fellow and served as 2013 OSA president. Currently she serves as a board member of the Canadian Association of Physicists and as an optics editor for the journal, Physics Reports.
