High-order harmonic generation yielding tunable extreme-ultraviolet radiation of high spectral purity
Production of extreme-ultraviolet radiation by high-order harmonic generation is demonstrated to yield unprecedented spectral purity of λ/Δλ=2.5×105 at wavelengths covering the entire range 40–100 nm. Tunability and sub-cm-1 bandwidth of the harmonics are demonstrated in recordings of the He (1s4p) and Ar (3p53d′) resonance lines at 52.2 and 86.6 nm. Frequency shift of the harmonics due to chirp-induced phenomena are investigated and found to be small, resulting in a frequency accuracy of about...[Show more]
