G�rard Mourou is a French pioneer in the field of electrical engineering and lasers. Along with Donna Strickland, he co-invented a technique called chirped pulse amplification, or CPA, which was later used to create ultrashort-pulse, very high-intensity laser pulses. In 1994, Mourou and his team at the University of Michigan discovered that the balance between the self-focusing refraction 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 has been the director of the Laboratoire d'Optique Appliquee at the ENSTA and is a professor at the �cole Polytechnique. He was the founding director of the Center for Ultrafast Optical Science at the University of Michigan in 1990. [More at Wikipedia]
