Chirped-Pulse Amplification
1985:
A paper published in Optics Communications by Donna Strickland and Gerard Mourou of LLE describes the chirped-pulse amplification (CPA), a technique used to amplify ultrashort laser pulses to the petawatt level. This approach, developed and demonstrated at LLE, is the basis of modern ultrahigh-power lasers.
