Abstract
We have investigated the efficiency of the fifth order harmonics from solid surface plasma by varying the electron density gradient using two 2.2 ps, 1054 nm laser pulses. A 5 ps time difference between the prepulse and main pulse results in an increase in the harmonic signal by a factor of 2–3, which then decreases for time delays greater than 10 ps. Experiments and calculations are presented that demonstrate a strong dependence of the conversion efficiency on the plasma scale length.
