WebThe pulse duration of the chirped pulse can be made up to 100 thousand times longer than the original pulse and its intensity is reduced accordingly. The chirped pulse, whose … Weball rely on chirped pulse amplification (CPA), underlining the importance of Mourou and Stricklands a’ ward winning breakthrough in the field of ultrafast phenomena. Multipass … 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. Some examples of these … See more There are several ways to construct compressors and stretchers.
