OBSERVATION OF MULTIPLE-HARMONIC RADIATION-INDUCED FROM A GOLD SURFACE BY PICOSECOND NEODYMIUM-DOPED YTTRIUM-ALUMINUM-GARNET LASER-PULSES

Illuminating a gold surface by strong (5 GW/cm2) picosecond neodymium-doped yttrium aluminum garnet laser pulses at grazing incidence, we observed generation of coherent beams of both even and odd harmonics up to fifth order in the reflected direction with efficiencies 10(-10) - 10(-13). The observe...

Zusammenfassung:	Illuminating a gold surface by strong (5 GW/cm2) picosecond neodymium-doped yttrium aluminum garnet laser pulses at grazing incidence, we observed generation of coherent beams of both even and odd harmonics up to fifth order in the reflected direction with efficiencies 10(-10) - 10(-13). The observed decrease of the harmonic efficiencies with increasing harmonic order is much weaker than predicted by perturbative theories.
