2019 Ta-You Wu Lecture in Physics | Generating High-Intensity, Ultrashort Optical Pulses

Dr. Donna Strickland, Professor, Department of Physics & Astronomy and Nobel Laureate, Physics 2018 (University of Waterloo)
Wednesday, October 30, 2019
4:00-5:00 PM
Rackham Auditorium Rackham Graduate School (Horace H.) Map
With the invention of lasers, the intensity of a light wave was increased by orders of magnitude over what had been achieved with a light bulb or sunlight. This much higher intensity led to new phenomena being observed, such as violet light coming out when red light went into the material. After GĂ©rard Mourou and I developed chirped pulse amplification, also known as CPA, the intensity again increased by more than a factor of 1,000 and it once again made new types of interactions possible between light and matter. We developed a laser that could deliver short pulses of light that knocked the electrons off their atoms. This new understanding of laser-matter interactions, led to the development of new machining techniques that are used in laser eye surgery or micromachining of glass used in cell phones.
