80 Low-Order Harmonic Generation in Plasma Plumes
The THG in beryllium plasma was reported in [48] and the
recommendations derived from those studies allowed for the
enhancement of higher order harmonics. In [15], we analyzed the
lowest HG in various plasmas using the femtosecond pulses, as well
as in the Mn, B, and In plasmas using the picosecond pulses.
In the case of 110 fs pulses, the lowest harmonic generated in
Mo and B plasmas was studied at different experimental conditions.
The influence of third harmonic intensity on the 110 fs pulse energy
showed a monotonic increase up to 3
