Abstract

The output from a wavelength-tunable optical parametric amplifer was used to generate high-order harmonics in a range of nobel gases. The phase-mathcing pressure and harmonic cut-off were recorded for each target gas at diffenent fundamental wavelengths. The experimental results are compared to a mo...
