Gérard Albert Mourou (born June 22, 1944) is a French scientist. He worked in electrical engineering and lasers.
With Donna Strickland, he won the Nobel Prize in Physics for their co-invention of a technique called chirped pulse amplification, or CPA.
In 1994, Mourou and his team at the University of Michigan discovered that the balance between Kerr effect and self-diffraction by ionization act as waveguides for the beam.
