Abstract

We demonstrate the first observation of significant resonance enhancement of a single high-order harmonic in the extreme ultraviolet region. Such intense harmonics are generated during the interaction of a femtosecond Ti:sapphire laser pulse with low-ionized indium ablation. A strong 13^th harmonic (61.2 nm) with conversion efficiency of 8×10^-5 and output intensity almost two orders of magnitude higher than neighbouring harmonics is demonstrated. Such an approach paves the way for efficient single-harmonic enhancement in the extreme ultraviolet range using different ablation sources.
