Abstract: The generation of UV third-harmonic radiation by a focused laser beam in a positively dispersive gaseous medium is investigated. The nonlinear gas is confined to a focal half-space by using a differentially pumped gas cell. The resulting density gradient along the beam axis is shown to provide an efficient frequency conversion in spectral regions ofpositive dispersion. Experimental results obtained in argon at 197nm, which compare favorably with theory, are presented.
