Abstract
The polarization of the VUV light generated by four-wave sum-frequency mixi ng process omega(4) = 2 omega(1) + omega(2) in mercury vapor at room temper ature is analyzed in detail. Due to the specific two-photon transition used to enhance the nonlinear process, the polarization of the VUV wave is show n to be identical to the polarization of the wave at the frequency wr. In p articular, circularly polarized VUV is observed with degree of circular pol arization exceeding 0.99.
