摘要：
At the Laser Centre Vrije Universiteit a table-top size, tunable and narrowband laser-based source of extreme ultraviolet radiation was developed using high-harmonic generation of powerful laser pulses of 300 ps duration and Fourier-transform limited bandwidth. The generated radiation has unprecedented spectral purity of lambda/Delta lambda > 2.5 x 10(5) at wavelengths covering the entire tunability range of 40-100 nm. The process of high-order harmonic generation was investigated in different gases (Ar, Kr, Xe, N-2) uncovering resonance phenomena for the conversion efficiency of specific harmonic orders.
