Abstract
The interaction of intense ultrashort laser pulses from a chirped pulse amplification titanium sapphire laser system with dielectric and metallic surfaces was studied. With a p-polarized incident beam and a large angle of incidence we have observed odd and even harmonics of high order with relatively smooth roll-off in the harmonic spectra. The shortest wavelength was 55.3 nm, corresponding to the 15th harmonic order.
