Harmonic generation from solid-vacuum interface irradiated at high laser intensities

• Observations of harmonic generation from solid Al targets irradiated at intensities of 1017 W/cm2 using a tabletop Ti:sapphire terawatt laser system are reported. For irradiances with laser light at a wavelength of [lambda] = 794nm (the fundamental frequency), harmonics up to the 7th, while for irradiances with frequency doubled laser light ([lambda] = 397) nm harmonics up to the 4th of the respective incident radiation were detected.
