Plenary Session

Donna Strickland

University of Waterloo

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.

Special Events

Technology Showcase: OPCPA Design and Manufacturing at Light Conversion

Monday, 04 October 10:00 – 10:20

Presenter: Valdas Maslinskas, Sales Engineer, Light Conversion, Lithuania

Description: LIGHT CONVERSION, is a pioneering manufacturer of femtosecond optical parametric amplifiers (OPAs) and Yb-based femtosecond laser sources. Currently, it is one of the world’s leading femtosecond laser producers. Products scale from compact industry-grade lasers to large multi-table scientific optical parametric chirped-pulse amplifiers (OPCPA).

OPCPA is the only currently available laser technology simultaneously providing high peak and average power, as well as few-cycle pulse duration required by the most demanding scientific applications. LIGHT CONVERSION answers these demands with a portfolio of OPCPA products based on years of OPA and laser development experience. 

Technology Showcase: Adjustable Mode Beam Laser Advantages for EV Welding Applications

Tuesday, 05 October 11:30 – 11:50

Presenter: Iurii Markushov, Senior Manager, Global Welding Applications, IPG

Description: To meet the demands and promise to deliver all electric fleets of vehicles in the next decade, auto manufacturers are challenged to find solutions that provide reliable, high-yield production while ensuring safe end-user components. Adjustable mode beam lasers are used to provide high-speed spatter-free welding of materials for electric motor components and EV batteries to meet the industry challenges. Low heat input laser welding offers the consistency and ability to control penetration depths to deliver welds that are porosity free with high surface quality across a wide range of material thicknesses. Combined with laser scan heads and real-time weld process monitoring, high-throughput laser welding with maximum quality assurance is achieved. Examples of laser welded copper, aluminum and steel will be presented.

Technology Showcase: OpticStudio STAR Module and Full System Modelling with the Zemax Suite

Wednesday, 06 October 08:00 – 08:20

Presenter: Esteban Carbajal, Sr. Product Manager, Zemax, United States

Description: Join Zemax Product Manager, Esteban Carbajal, as he highlights the power of the new OpticStudio STAR module and how it integrates into the Zemax suite for end-to-end optical product development. This talk will cover how complex thermal and structural effects can be understood in high-power laser systems and how Zemax tools empower intelligent design decisions and streamlined workflows:

Easily build STOP analysis into your optical design workflows. Get fast, accurate STOP results with confidence. Analyze the impact of structural and thermal loads on your optical designs with the OpticStudio Structural, Thermal, Analysis and Results (STAR) module. Extend OpticStudio’s capabilities to include structural, thermal, and optical performance (STOP) analysis based on finite element analysis (FEA) datasets. Reduce human error and wasted time spent aligning coordinate systems with visualizations and analyses that bring STOP analysis and OpticStudio into an integrated workflow.

• Import FEA data from any FEA package

• Perform numeric fitting with one-click

• Assess performance impact

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.
