Chirped pulse amplification Chirped pulse amplification Chirped pulse amplification (CPA) is a technique for amplifying an ultrashort laser pulse up to the petawatt level with the laser pulse being stretched out temporally and spectrally prior to amplification. CPA is the current state-of-the-art technique used by all of the highest power lasers (greater than about 100 terawatts) in the world, with the exception of the ≈500 TW National Ignition Facility. Some examples of these lasers are the Vulcan laser at the Rutherford Appleton Laboratory's Central Laser Facility, the Diocles laser at the University of Nebraska–Lincoln, the GEKKO XII laser at the GEKKO XII facility
