WebChirped-pulse amplification (CPA) technique has been widely used to generate ultra-intense femtosecond pulses. In this scheme, the seed pulses from an oscillator are stretched before amplification, usually by introducing a positive chirp, and afterwards compressed with an equally large negative chirp[1]. The stretched pulses, WebIn a chirped-pulse amplification (CPA) system, the pulse duration within the optical amplifier needs to be increased in order to reduce the peak power, which would otherwise cause problems e.g. with nonlinear pulse distortion. In extreme cases, pulses with original durations of the order of 10 fs, for example, are stretched to durations of ... diamond head mortuary addressWebChirped-pulse amplification (CPA) [1] of ultrashort light pulses in solid-state lasers and parametric amplifiers has permitted the generation of optical pulses with multi-gigawatt to multi-terawatt peak powers and holds promise for scaling high-power laser technology far beyond the petawatt frontier [2–4]. ... diamond head mission bc
