Abstract

We report the first experimental results on a high-gain harmonic-generation (HGHG) free-electron laser (FEL) operating in the ultraviolet. An 800nm seed from a Ti-Sapphire laser has been used to produce saturated amplified output at the 266nm third-harmonic. The results confirm the advantages of the HGHG FEL: stable central wavelength, narrow bandwidth and small pulse energy fluctuation. The harmonic output at 88nm, which accompanies the 266nm radiation, has been used in an ion pair imaging experiment in chemistry.
