Abstract
We report on the design details of the first ultraviolet (UV) free-ele ctron laser (FEL) oscillator driven by low-energy electrons from a rad io-frequency linear accelerator. In our experiment we used a high-curr ent, high brightness electron beam in combination with a wiggler of no vel design to produce an FEL that lased at wavelengths from 369 to 380 nm using 45.9-45.2 MeV electrons. In addition we performed a proof-of -principle experiment that demonstrated the first ever photolithograph y on a photoresist-coated silicon wafer using an FEL light source.
