چکیده
|
We investigate theoretically thehigh-order harmonic spectrum extension andnumerical generation of an intense isolatedattosecond pulse from he+ ion irradiated by atwo-color laser field. our simulation resultsshow that the chirp of the fundamental field cancontrol hhg cutoff position. also, these resultsshow that the envelope forms of two fields areimportant factors for controlling the resultantattosecond pulses. besides, the effects of relativeintensity are investigated. as a result, by usingthe optimized conditions an intense isolated 126-as (attosecond) pulse can be observed.
