摘要: We propose a scheme that combines the echo-enabled harmonic generation technique with bunch compression and allows one to generate numbers of few hundred in microbunched beam through up-conversion frequency an ultraviolet seed laser. A few-cycle intense laser is used required energy chirp for selection attosecond x-ray pulse. Sending this short undulator results isolated Using representative realistic set parameters, we show 1 nm pulse peak power MW duration as 20 attoseconds (FWHM) can be generated from 200 The proposed may enable study electronic dynamics resolution beyond atomic unit time ($\ensuremath{\sim}24$ attoseconds) open new regime ultrafast sciences.
