Abstract :
We investigate theoretically the
high-order harmonic spectrum extension and
numerical generation of an intense isolated
attosecond pulse from He+ ion irradiated by a
two-color laser field. Our simulation results
show that the chirp of the fundamental field can
control HHG cutoff position. Also, these results
show that the envelope forms of two fields are
important factors for controlling the resultant
attosecond pulses. Besides, the effects of relative
intensity are investigated. As a result, by using
the optimized conditions an intense isolated 126-
as (attosecond) pulse can be observed.
