Chirped pulse amplification italiano
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, then amplified, and then compressed again. The stretching and compression uses devices that ensure that the … See more Before the introduction of CPA in the mid-1980s, the peak power of laser pulses was limited because a laser pulse at intensities of gigawatts per square centimeter causes serious damage to the gain medium through See more CPA is used in all of the highest-power lasers (greater than about 100 terawatts) in the world, with the exception of the ≈500 TW National Ignition Facility.
