Using only one dye laser, efficient generation of VUV radiation (10 13 photons/pulse) is demonstrated at 125.140 nm and 125.053 nm by four-wave sum-frequency mixing in a room-temperature mercury vapor. The emission at 125.053 nm, which is out of twophoton resonance but near three-photon resonance, has been observed for the first time and is carefully analyzed. In particular, numerical calculations have been carried out for gaussian pump beams taking into account absorption of VUV photons anddoi:10.1109/2944.473677 fatcat:cxfqtzw6vvbx5gc3r24vjadw4u
