WebLaser pulse compression is also employed in chirped pulse amplifiers (CPAs). CPAs are used to amplify ultrashort laser pulses safely, as their high peak powers would cause rapid and catastrophic damage in … 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 different color … 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 See more There are several ways to construct compressors and stretchers. However, a typical Ti:sapphire-based chirped-pulse amplifier requires that the pulses are stretched to several hundred picoseconds, which means that the different wavelength components must … See more • Physics portal • Technology portal • Femtotechnology • Group velocity • Mode locking See more
WebAug 3, 1999 · For example, the excitation pulse might be a femtosecond linear chirped laser pulse, which can interact with the wave packet through a so-called intra-pulse pump–dump process. A negatively chirped pulse (frequency components shift in time from blue to red) might be tailored to maintain resonance with the wave packet as it evolves … WebDefine chirped pulse. chirped pulse synonyms, chirped pulse pronunciation, chirped pulse translation, English dictionary definition of chirped pulse. n. ... a physics Nobel …
