Gérard Mourou
Appearance
Gérard Mourou is a French pioneer in the field of electrical engineering and lasers. He invented a technique called chirped pulse amplification, or CPA, which was later used to create ultrashort-pulse, very high-intensity (terawatt) laser pulses. In 1994, Mourou and his team at the University of Michigan discovered that the balance between the self-focusing refraction (see Kerr effect) and self-attenuating diffraction by ionization and rarefaction of a laser beam of terawatt intensities in the atmosphere creates "filaments" which act as waveguides for the beam thus preventing divergence.
He is currently the director of the Laboratoire d'Optique Appliquee in France.
