Abstract
We have investigated the generation of high-order harmonics of a KrF e xcimer laser (80 mJ, 0.5 ps) in rare gases (He, Ne) and molecular gase s (N-2, O-2) The highest-order harmonic of the 37th (6.7 nm) has been observed in He, and of the 29th (8.6 nm) in N-2 and O-2. Our experimen tal results suggest that the high-order harmonics are emitted from ion ized atoms. The maximum photon energy of the high-order harmonics may be restricted by phase mismatching caused by free electrons.
