Learn about Donna Strickland, Nobel-winning Canadian physicist and pioneer of ultrafast lasers. Discover her early life, scientific breakthroughs, awards, quotes, and legacy.

Introduction

Donna Theo Strickland (born May 27, 1959) is a Canadian physicist, best known for co-inventing the technique of chirped pulse amplification (CPA), which allows for generating extremely intense, ultra-short laser pulses.

In 2018, she shared the Nobel Prize in Physics with Gérard Mourou (her PhD supervisor) and Arthur Ashkin for their work in laser physics.

Strickland’s contributions have had far-reaching impact in physics, medicine (for example in eye surgery and precision micromachining), and instrumentation, while her own career story is also inspiring for women in science.

Early Life and Education

• Donna Strickland was born in Guelph, Ontario, Canada, in 1959.

• Her father was an electrical engineer; her mother had training as a teacher.

• From a young age, she enjoyed school and had a strength in mathematics and physics.

• In high school, she encountered gender stereotypes—one teacher told her math and physics were “boys’ subjects”—but she pushed past that.

University and Doctoral Work

• She obtained a Bachelor’s degree in Engineering Physics from McMaster University in Hamilton, Ontario, in 1981.

• She then went to the University of Rochester (USA) for graduate work in optics. Her PhD was completed in 1989, working with Gérard Mourou.

• Her doctoral research led to the development of the chirped pulse amplification (CPA) technique—the key innovation for which she is best known.

Scientific Work & Major Contributions

Chirped Pulse Amplification (CPA)

The central scientific achievement of Strickland’s career is CPA. The problem CPA addresses is: how to amplify ultrashort laser pulses to very high intensity without destroying the amplifying medium (because the peak power is too high). The solution:

1. Stretch the pulse in time (thus reducing its peak power)

2. Amplify the stretched pulse

3. Compress it back to short duration

By doing so, one can reach very high peak powers in a safe way.

The technique has enabled advances in:

• Precision laser surgery (such as for eyes)

• Material processing and micromachining

• Various high-field physics and nonlinear optics applications

• Fundamental research using extremely intense laser fields

Career Positions & Affiliations

• After her PhD, Strickland worked as a Research Associate at the National Research Council of Canada (1988–1991).

• She then moved to the Lawrence Livermore National Laboratory (1991–1992).

• Then she joined Princeton University in their Advanced Technology Center for Photonics and Opto-electronic Materials (from 1992 to 1997).

• In 1997, she became a faculty member at University of Waterloo, Canada, where she has held a position in the physics department.

Over the years, Strickland continued to lead work in ultrafast lasers, extending CPA techniques, exploring new wavelength regimes, and pursuing applications in optics and photonics.

Awards, Recognition & Significance

• In 2018, Donna Strickland and Gérard Mourou received the Nobel Prize in Physics, shared with Arthur Ashkin. The award recognized their transformative work in laser physics (CPA).

• She was the third woman ever to receive the Nobel Prize in Physics (after Marie Curie and Maria Goeppert Mayer).

• Her invention has become foundational in many scientific, medical, and industrial laser applications.

• Her career stands as a role model, especially for women and underrepresented groups in STEM, demonstrating that rigorous science and long-term curiosity can lead to breakthroughs and recognition.

Personality, Style & Perspective

Donna Strickland is known for humility, curiosity, and persistence. Some notable traits drawn from her remarks:

• She often refers to “playing with lasers” — showing that she retains a playful and experimental spirit.

• She has spoken about being quiet or shy during her early years, and carrying doubts, but focusing on her strengths in math and physics.

• She has expressed the view that she doesn’t think of herself primarily as a “woman in science,” but simply as a scientist.

• She supports greater recognition of women in physics and more equitable opportunities, while also being cautious against tokenism.

Her style is modest, grounded, and focused on substance over showmanship.

Notable Quotes by Donna Strickland

Here are a selection of memorable quotes attributed to her:

“We must give scientists the opportunity through funding and time to pursue curiosity-based, long-term, basic-science research.” “The most fun part of my day is when I get to play with my lasers.” “But I don’t see myself as a woman in science. I see myself as a scientist.” “If somebody else thinks something that you don’t believe in, just think they're wrong and you're right and keep going. That’s pretty much the way I always think.” “Because the high-intensity pulses are short, the laser only damages the area where it’s applied. The result is precise, clean cuts that are ideal for transparent materials.”

These reflect her passion for science, her confidence in her work, and her candid approach to identity.

Lessons from Donna Strickland’s Journey

From her life and work, we can draw lessons valuable to scientists, students, and anyone pursuing depth in their field:

1. Curiosity & patience matter
   Her breakthrough work (CPA) came through persistent, curiosity-driven research rather than fast trends.

2. Focus on strengths
   She recognized early that her strongest path was physics/math, even if other fields were less natural for her—and she leaned into that strength.

3. Humility & balance
   Despite being a Nobel laureate, she emphasizes the importance of continuing to learn, experiment, and enjoy the process.

4. Resist stereotypes, but don’t let them distract you
   When confronted with bias or social expectations (e.g. “women’s roles”), she persisted in doing quality work rather than being defined by labels.

5. Support basic science
   She advocates for funding and time for fundamental research—discovery doesn’t always have immediate applications, but can yield transformative tools later.

6. Be yourself
   Her quote “There’s no point in me being something other than me” (among her quotes) suggests that authenticity and consistency are part of sustained work.

7. Encourage inclusion without tokenism
   She recognizes the value of highlighting women and underrepresented scientists, but also the dangers of reducing people to categories rather than recognizing them as scientists first.
