WebDec 31, 2024 · We survey current status of chirped-pulse amplification development and its applications. We start with the review of optical compressor and stretcher as well as the amplification techniques. 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 intensity is now below the damage threshold of gigawatts per square centimeter, can be amplified safely by a factor 10 6 or more.
