Donna Strickland

Donna Strickland is one of the most consequential physicists of the modern era — the scientist whose breakthrough invention made today’s high-intensity laser technology possible. A professor in the Department of Physics and Astronomy at the University of Waterloo, she is one of only three women in history to have received the Nobel Prize in Physics, following Marie Curie in 1903 and Maria Goeppert Mayer in 1963. Her distinction is not merely symbolic: the technique she co-invented has transformed industries ranging from medicine to manufacturing.

Nobel Prize speaker Donna Strickland is best known for co-developing chirped pulse amplification (CPA) — a technique she pioneered as a PhD student at the University of Rochester alongside her supervisor Gérard Mourou. Published in 1985, their breakthrough solved a fundamental problem in laser physics: how to amplify the power of laser pulses without destroying the amplifying medium. By stretching a pulse in time, amplifying it, and then compressing it back down, they generated ultrashort, ultra-high-intensity pulses of previously unattainable power. The result was what Strickland herself describes as a “laser hammer” — one that can cut through transparent materials like the human cornea or the glass inside a cell phone, feats that were simply impossible before CPA.

The real-world applications are vast and growing. CPA is the foundational technology behind LASIK and laser eye surgery procedures performed on millions of patients annually. It drives precision micromachining for consumer electronics. It powers cutting-edge research into cancer treatment, extreme-light physics, and the generation of attosecond pulses for probing molecular dynamics. Strickland received the 2018 Nobel Prize in Physics for this work, and continues to lead her ultrafast laser group at Waterloo — now focused on next-generation applications including treating presbyopia and exploring mid-infrared pulse generation.

Pioneer, Professor, and Symbol of What Science Can Look Like

Beyond the laboratory, Strickland’s career carries broader significance. She served as President of Optica (formerly OSA) in 2013 and is a fellow of Optica, the Royal Society of Canada, SPIE, and an honorary fellow of the Canadian Academy of Engineering and the Institute of Physics. She holds the Companion of the Order of Canada, France’s Chevalier de la Légion d’honneur, and was elected a Corresponding Member of the Australian Academy of Science. Her research group at Waterloo — which she first joined in 1997, becoming the institution’s first full-time female physics professor — remains a global reference point for ultrafast laser science.

As a speaker, Donna Strickland delivers something rare: a Nobel laureate who combines deep scientific authority with genuine warmth and accessibility. She engages audiences on the elegance of discovery — how a three-page paper written by a graduate student became the backbone of a global industry — and speaks compellingly about curiosity-driven research, the long road from lab bench to real-world impact, women in science, and what it means to build a career around ideas rather than accolades. Senior audiences leave with a refreshed perspective on innovation, resilience, and the unexpected paths that change everything.
