Abstract
Investigations have been performed on the spatial distributions of high-order generation from solid surface plasmas. It is found that the divergence of the harmonics gradually increases at intensities between I(lambda) 2 equals 2 X 1015 and 2 X 1016 X cm-2 X micrometers 2 ps, 1054 nm laser pulse with typical maximum intensities of approximately 2 X 1017 W X cm-2. We experimentally observe that the divergence of the harmonics decreases as the order of the harmonic increases. We also measured that the divergence of the third harmonic emission is smaller for 2.2 ps width lasers as compared with those for 100 ps pulse width lasers.
