From Nonlinear Optics to High-Intensity Laser Physics
The laser increased the intensity of light that can be generated by orders of magnitude and thus brought about nonlinear optical interactions with matter. Chirped pulse amplification, also known as CPA, changed the intensity level by a few more orders of magnitude and helped usher in a new type of laser-matter interaction that is referred to as high-intensity laser physics. In this talk, I will discuss the differences between nonlinear optics and high-intensity laser physics. The development of CPA and why short, intense laser pulses can cut transparent material will also be included. I will also discuss future applications.
About the Speaker
Donna Strickland is a professor in the Department of Physics and Astronomy at the University of Waterloo and is one of the recipients of the Nobel Prize in Physics 2018 for developing chirped pulse amplification with Gérard Mourou, her PhD supervisor at the time. They published this Nobel-winning research in 1985 when Strickland was a PhD student at the University of Rochester. Strickland earned a B.Eng. from McMaster University and a PhD in optics from the University of Rochester. Strickland was a research associate at the National Research Council Canada, a physicist at Lawrence Livermore National Laboratory and a member of technical staff at Princeton University. In 1997, she joined the University of Waterloo, where her ultrafast laser group develops high-intensity laser systems for nonlinear optics investigations. Strickland served as the president of Optica in 2013 and is a fellow of Optica, SPIE, the Royal Society of Canada and the Royal Society. She is an honorary fellow of the Canadian Academy of Engineering and the Institute of Physics and an international member of the US National Academy of Science. Strickland was named a Companion of the Order of Canada.
Shaping the Future with Photonics and Advanced Materials
From the invention of lasers in 1960, advances in materials and high-energy optical coatings have enabled a continuous stream of performance improvements. This progress has brought lasers to the forefront of metrology and manufacturing, and enabled processing of ever-more advanced materials such as diamond and silicon carbide. This trend continues as photonics takes center stage in the defining technology shifts of our era, from 3D sensing to laser additive manufacturing, EUV systems, and beyond. We will examine the megatrends driving these changes and what the future holds for them.

Technology Showcase: Improving USP Laser Reliability Through the Innovative Approach to Laser Cooling
Wednesday, 06 October 08:20 – 08:40
Presenter: Aldas Juronis, OEM Lasers Program Manager, EKSPLA, Lithuania
Description: FemtoLux 30 is the new femtosecond laser which employs an innovative cooling system and sets new reliability standards among industrial femtosecond lasers.
Other lasers of similar optical power use water for cooling, which means an additional bulky and heavy water chiller is needed. The chiller requires periodical maintenance. Moreover, in the unfortunate event of water leakage other equipment could be damaged. Instead of using water for transferring heat from a laser head, the FemtoLux 30 uses an innovative Direct Refrigerant Cooling method.
Refrigerant agent circulates from a compressor and condenser, that are integrated together with the PSU, to a cooling plate via armored flexible lines. The cooling plate is detachable from the laser head for more convenient laser installation.
The FemtoLux 30 femtosecond laser has a tunable pulse duration from <350 fs to 1 ps and can operate in a broad AOM controlled range of pulse repetition rates from a single shot to 4 MHz.
Maximum pulse energy is more than 90µJ operating with single pulses, but could be as high as 250µJ, while operating in a burst mode.
PhD-Level Transferable Skills That Stand Out During Economic Downturns (& How To Communicate Them Virtually)
Wednesday, 06 October 11:00 – 12:00
The global management consulting firm McKinsey & Company recently released a report showing that there is a 20% deficit in the job market for job candidates who can do two things - research, and analysis. These two transferable skills are key skill that all PhDs have regardless of their background and makes them highly valuable job candidates, especially in times of uncertainty. In this webinar, we will detail the top 10 transferable skills that PhDs need to communicate on their resume and during their job search as a while, as well as the 3 categories of core competencies that PhDs must master and leverage in order to get hired in industry.
