Plenary Session

Jan Kleinert

MKS Instruments, Inc.

From µs to fs, kHz to GHz: laser micromachining in the microelectronics industry

The ever increasing performance of everyday electronics causes a relentless drive for 'faster, better, cheaper' laser based manufacturing technologies. Understanding the underlying highly nonlinear laser material interaction dynamics is key to keeping pace.

About the Speaker

Jan Kleinert is the Research Director at Electro-Scientific Industries (ESI), a division of MKS, and a member of the Office of Chief Technology Officers at MKS. He received his undergraduate education at the Ruprecht Karls Universitaet in Heidelberg, the University of Oklahoma, and the Max Planck Institute for Nuclear Physics in 2002 and his PhD from the University of Rochester, NY in 2008. After joining ESI in 2008, one of his early projects involved the world's first successful high volume deployment of high power ultrafast lasers in an industrial, 24/7 manufacturing environment in early 2010. Heading the research department since 2012 his focus has been to expand the scope from application experiments to understanding the underlying physics through numerical modelling and pushing the boundaries of high bandwidth laser beam positioning.

Peter F. Moulton

MIT Lincoln Laboratory

A Journey through 60 Years of Solid State Lasers

The first laser, demonstrated in 1960, was based on the solid state material ruby. After 60 years of laser development, solid state lasers have achieved a dominant role in both scientific and industrial applications. We review how this all happened, and consider the future.

About the Speaker

Dr. Moulton is a member of the Senior Staff in the Laser Applications and Applications Group at the MIT Lincoln Laboratory in Lexington, MA. He received an A.B. in Physics from Harvard College in 1968 and M.S. and Ph.D. degrees in Electrical Engineering from MIT in 1972 and 1975 respectively. After graduate school he worked in the Quantum Electronics Group at Lincoln Laboratory. In 1985 he helped to found Schwartz Electro-Optics, where he managed the Research Division and worked to spin that out a separate company, Q-Peak, now part of Physical Sciences. He rejoined Lincoln Laboratory in 2015. Moulton's technical work began in the field of bulk solid state lasers, later extended to include nonlinear optics and fiber lasers. At Lincoln Laboratory in 1982 he invented the Ti:sapphire laser, and he has also made important advances in high-power diode-pumped solid state lasers, parametric oscillators, and long-wavelength bulk and fiber lasers.


Special Events

OIDA / OSAF Virtual Networking & Career Development

Monday, 12 October 13:00 – 14:00

Join us virtually for this unique opportunity for students and early career professionals, who are close to finishing or who have recently finished their doctorate degree, to interact with key industry and academic leaders in the community. Students interested in all career paths – from those seeking an academic position, wishing to start a technology business, or someone interested in government/public service, to those looking to translate their bench work skills to product development – are encouraged to register.  Students will “sit” at a table and have an opportunity to discuss their ongoing research and career plans with the attending leaders, while they will share their professional journey and provide professional development and career advice. Attendees will move “ around the room” and engage with at least three professionals during the program.

Women of Laser Meet and Greet

Tuesday, 13 October 10:00 – 10:30

Grab your coffee, soda or beverage of your choice and join other women of the Lasers Conference for an informal virtual get together. Sources Subcommittee Program Chair, Clara Saraceno, from Ruhr Universität Bochum, Germany, and other committee members will be on hand to answer any questions you may have. Or just log in to learn a bit about OSA’s diversity and inclusion efforts and share your ideas on helping ensure our community and this meeting is as welcoming and inclusive as possible. We would want this program to be an interactive as possible so you will be able to turn your camera and mic on or off to participate as you choose.

Coffee Break: How to Monitor Laser System Performance with Power Measurement

Tuesday, 13 October 10:00 – 10:30

Does your laser system always produce the exact same output? The laser itself, the optical components in your system and also the surrounding environment, all have an impact on the output and efficiency of your processes. To ensure consistent, repeatable results, it is important to track your system’s health at various checkpoints. Do you know how to measure it?

In this hot topic discussion, a laser beam measurement expert will discuss the importance of power measurement, how to measure your laser’s power accurately and how the right tools can help you track your laser system’s performances easily before problems arise. The basic principles for laser power measurement will be presented, both for continuous monitoring and spot-check measurements.

The Center for Optics, Photonics and Lasers Virtual Tour

Thursday, 15 October 12:30 – 13:30

The OSA Laser Congress has organized a virtual tour at The Center for Optics, Photonics and Lasers (COPL) at the Université Laval. Visit the facility and hear directly from the scientists and researchers on the work they are doing. After the tour, ask questions of members of COPL about their facility.

About twenty research teams conduct their activities and dedicate research solely to optics and photonics in this 10,000 m2 building that opened in 2006. Lab space in a clean room environment takes up two thirds of the area. The Center is equipped with fiber-optic fabrication and characterization facilities, optical engineering laboratories, opto-mechanical fabrication facilities, thin film deposition systems, advanced fiber laser development laboratories and sophisticated optical test and measurement instruments. The COPL currently trains over 150 graduate students, most of whom go on to join the hundred or so companies specializing in optics and photonics in the Greater Quebec City area.

Awards Ceremony and Farewell

Friday, 16 October 15:30 – 16:00

The OSA Laser Congress recognizes the next generation of scientists through a student presentation competition. After presenting the paper at the conference, the Program Committee members select winners based on content quality, value to the technical community of interest and the students' presentation skills.

Join the Laser Congress Chairs as they announce the winners of the student presentation competition and wrap the 2020 Laser Congress up with a look back at highlights from the Congress and look forward to the 2021 Laser Congress.
