High VUV powers, up to 2.5 kW at 133 nm, are obtained from two-photon-resonant, difference-frequency generation in hydrogen by using an ArF excimer laser and a frequency-doubled Nd:YAG-pumped dye laser. This radiation is used to perform two-photon excitation of neon at greater than 150000 cm−1 , the shortest two-photon transition yet accessed to our knowledge.
