title: Resonantly enhanced second-harmonic generation in zinc vapor.
abstract: Coherent second-harmonic radiation has been generated in atomic zinc vapor at 1792.5 and 1601 A from the 5(1)S(0)and 4(1)D(2) states, respectively, by two-photon resonance enhancement. Measurements of the ratio of second-to third-harmonic generation suggest the occurrence of static electric fields of ~5 kV/cm. These fields are caused by ionization of ~2% of the atoms in the focal volume of the incident laser beam.
