Аннотация

We report the high-order harmonic generation of up to the 33rd harmonic (λ = 24.1 nm) of Ti : sapphire laser radiation from the prepulse-produced aluminium plasma. The plateau pattern for high harmonics was observed, contrary to the steep decrease in harmonic output appearing in the case of carbon plasma under analogous conditions. The harmonic generation appeared to be efficient in the case of singly ionized Al plasma when the high-charged ion concentration was negligible. The conversion efficiency for the 25th harmonic was measured to be 2× 10−6, which was twenty times higher when comparing to the case for boron plasma. The comparison of the harmonics generating from the Al and Al2 O3 plumes showed equal conversion efficiencies and cutoff harmonics.
