Application of beryllium plasma for the harmonic generation of Ti:sapphire laser radiation

We report the studies of the low- and high-order harmonic generation (HHG) in beryllium plasma using the Ti:sapphire laser radiation (790 nm) and its second harmonic (395 nm). We achieved the tuning of HHG spectra by tuning the nonlinear optical crystal used for the second harmonic generation of fundamental radiation. The role of restricting factors during the HHG in a beryllium plume is discussed.
